2.3.1 Radio Assembly Power
Referring to Figure 3, the Radio assembly unit
receives two separate 13.8 VDC power inputs
from a “T800 Slimline” dual power supply typically rack-mounted right below the main assembly radio chassis.
The T800 is made up of two separate power
supply units joined in a single chassis:
•
A T807 using convection cooling is rated up
to 15A. It supplies all the radio modules
other than the Power Amplifier.
•
A T808 using convection and fan cooling is
rated up to 25A. It supplies only the Power
Amplifier module.
Normally used at room ambient temperatures,
they can operate within specifications over a
range of –10 to +60 °C.
Note: Internal over-temperature protection
shuts down the main transformer above
105 degrees Celsius.
Both power supply modules are internally connected to ground via their individual, rearconnected, seven-foot standard 120 VAC power
cords. Nevertheless, each requires a separate
secure electrical ground connection. Individual
grounding tabs are provided next to the power
connectors.
Similarly, the Radio Assembly chassis requires
a secure ground connection. A threaded
grounding binding post fitted with a knurled
binding-nut is provided on the chassis next to
DC input 2.
Separate grounding leads with appropriate connectors are supplied (either in the courtesy
small-parts kit or with one end fastened to the
equipment.
A- For each of the power supply modules:
1. Fit one end of the grounding lead’s
push-on connector onto the
grounding tab.
B- For the Radio Assembly chassis:
1. Install the grounding lead’s lug over
the binding post and firmly handtighten the binding-nut.
120 20170-200
Caution:
Improper grounding between power
supply case and rack frame may result
in harmful voltage potentials and/or
miscellaneous power supply switching
noise problems in both receivers and
transmitter.

Important note:
The aggregate total baud rate for all active
ports on a BDLCPD must not exceed 30,000
for ParagonPD. Sustained simultaneous operation on devices 1 and 3, using the factory
settings for these ports, may result in lost
characters.
Using the factory settings, device 3 is intended only for use during configuration and
should not be used simultaneously with data
traffic on device 1. For special user application done while the BDLCPD is active, use
either device 2, or set device 3 to 2400
bauds.
The Radio Installation Software (RIS) program
is used to:
•
Check and troubleshoot ParagonPD.
•
Save an existing configuration.
•
Upload files for field configuring of units

ParagonPD Technical Manual
WARNING: Do not attempt to re-tune the IF stages (i.e. L312 to L318).
These adjustments do not need to be re-adjusted after frequency re-programming.
Touching these coils will have a direct impact on the DSP modem coefficient settings
and may significantly reduce the radio performances over data.
6.2.2.4
SINAD and Linearity Check
1. Apply the following settings to the IFR:
Generator mode, Output T/R
IFR TX frequency to match the main radio RX frequency
Filter set to wide band (no audio filter)
Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off, except for “wideband”.
Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm (including
cable loss).
3. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) above the main radio
RX frequency, record the SINAD reading. It should remain within 1.5dB from the on frequency
SINAD reading.
4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio
RX frequency, record the SINAD reading. It should remain within 1.5dB from the on-frequency
SINAD reading.
Note:
If one of the above requirements is not met, try to re-tune the front-end. If it is still “failed”,
contact your Dataradio technical support.
6.2.2.5
RSSI Adjustment
Note: This check is only recommended for ParagonPD model running DBA protocol 3.06.009 series or
later.
1. Apply an on-channel signal from the RF generator at a level of -110dBm with deviation of
±3kHz (full channel) or ±1.5kHz (half channel) at 1kHz tone.
2. Adjust RV301 (RSSI level) to give 2.0V RSSI output when measured with a multimeter at
SK301 pin 2 or on the relevant backplane board at SK1 pin 5 (see Figure 30 for test point location).
3. Vary the RF level in 10dB steps and check that the RSSI output voltage changes at a rate of a
10dB/V (±0.20VDC) over the range of –120dBm to –80dBm. If the requirement cannot be
reached, contact your Dataradio technical support.

6.3.3 Channel Selection via DIP Switches
The backplane-mounted DIP switch settings override the default channel programmed by
PGM800Win.
To set a default channel via the software, all DIP switches must be set to “OFF” (i.e. 00000000).
When a switch is “Off”, its binary count is active; when a switch is “ON” its binary count is inactive.
The various DIP switch combinations of ON or OFF make up a binary total, which identifies the
channel number. To select a channel, set the appropriate DIP switch or switches to “OFF” to
make the binary count total the channel number you want. Set all other switches to “ON”.
It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings.
Example: To select channel 5, set the DIP switches as shown in below:

3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again.
(minimum requirement to reach is 12dB SINAD for -110dBm)
4. Perform the SINAD linearity tests described in paragraph 6.4.2.4. If it fails to pass the requirement, contact your Dataradio technical support.
WARNING: Do NOT attempt to re-tune the IF stages
(i.e. L310 to L390 for T855, CV318 or L330 to L360 for T835).
These adjustments do not need to be re-adjusted after frequency reprogramming. Touching these coils will have a direct impact on the modem
DSP coefficient settings and may reduce significantly the radio performances
over data.
6.4.2.4
SINAD and Linearity Check
1. Apply the following settings to the IFR:
a) Generator mode, Output T/R
b) IFR TX frequency to match the main radio RX frequency
120 20170-200

ParagonPD Technical Manual
c) Filter set to wide band (no audio filter)
d) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off.
e) Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.
f) Use a X1 scope probe connected to IFR SINAD input and monitor the Discriminator O/P
on the backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at
the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835)
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm (including cable loss).
3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1dB from the on frequency SINAD reading. For T855, use above values, for T835 use 1.5kHz (full channel) or
0.8kHz (half channel).
4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main
radio RX frequency, record the SINAD reading. It should remain within 1dB from the onfrequency SINAD reading. For T855, use above values, for T835 use 1.5kHz (full channel)
or 0.8kHz (half channel).
Note: If one of the above requirements is not met, try to re-tune the front-end. It
still failed, contact your Dataradio technical support.
6.4.2.5
RSSI Adjustment (UHF: T855)
Note: This check is only recommended for Paragon/R model running DBA protocol 3.06.009
series or later.
Apply an on-channel signal from the RF generator at a level of -110dBm with deviation of
±3kHz (full channel) or ±1.5kHz (half channel) at 1kHz tone.
Adjust RV320 (RSSI level) to give 2.0V RSSI output at SK330 pin 2 or on backplane SK1
pin 5 when measured with a voltmeter (See Figure 30).
Vary the RF level in 10dB steps and check that the RSSI output voltage (SK1 pin5) changes
at a rate of a 10dB/V (±0.20VDC) over the range of –120 dBm to -80dBm (see Figure 28). If
the requirement cannot be reached, contact your Dataradio technical support.

6.4.3.2
Synthesizer Alignment
Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the
synthesizer loop voltage).
1. T857 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC.
2. T837 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC.
Multiple channels:
1. T857 (UHF) Adjust the VCO loop to 10V using the middle channel.
2. T837 (VHF) Adjust the VCO loop to 9V using the middle frequency channel.
All channels should lie within the upper and lower limits of 16V and 3V respectively for
the T857 and within 13V and 5V for the T837.
Note:
Normally, the fast TX key option is installed and the synthesizer is always energized. In the case where that option was not fitted, we must key the transmitter by
pressing the front panel Carrier button to make the above adjustment possible.
6.4.3.3
TX Frequency Error Adjustment
1. Apply the following settings to the IFR:
- Receiver mode
- IFR RX frequency to match the main radio TX frequency
- IF Filter set to 30KHz
- Zoom the RF Error window: select 10Khz range
120 20170-200

ParagonPD Technical Manual
2. Key the transmitter by pressing the front panel TX-Key button and measure the carrier
output frequency. It should be within ±300 Hz. If it is not, adjust the TCXO to trim to
meet the requirement, preferably within 100Hz.
6.4.3.4
Low-Frequency Balance Adjustment
PGM800Win controls this adjustment. Electronic potentiometer (256 step) is used to allow
channel adjustment of two-point modulation (Low freq. balance).
1. Apply the following settings to the IFR:
– Receiver mode and Oscilloscope display (Source Demod out connector, DC coupled).
– IFR RX frequency to match the radio transmit frequency
– IF Filter set to 30KHz
– Zoom the Deviation window: select 10kHz Range and DC coupling.
2. Select the active or, the lowest (in the case of multi-channel base) frequency channel (via
dip switch)
3. Transmit a square wave by pressing the BDLCPD’s PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or run on another computer the RIS program and
press the Flatness test button. You can also run both programs on the same computer if
two serial COM ports are available.
4. Adjust IC220 via PGM800Win “reference modulation” to obtain the best square wave,
no damping, no overshoot. (You can use either the mouse or up and down arrow keys).
Record the deviation read.
5. If transmission has not ended by itself, press BDLCPD PF1 or press RIS’ Flatness test
button to stop it. For single-channel unit, proceed to step 7.
6. For multi-channel unit, select the highest frequency channel. Transmit a square wave by
pressing the BDLCPD’s PF1 button and following the procedure outlined in section
3.2.1.1.2.2 or run on another computer the RIS program and press the Flatness test button. Record deviation again.
7. The difference in deviation between the two channels should be less than ±300Hz. If not,
re-adjust IC220 to "average" the square wave shape on both channels until the spec is
met.
8. To confirm the adjustment, select the active, or the lowest frequency channel. Compare
the deviation produced between:
- TX ON (Modulated) and
- Random data tests,
The difference should be lower than 300 Hz. For multi-channel unit, repeat this step on
the highest frequency channel.
8. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing
the BDLCPD’s PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or
run on another computer the RIS program and press the TX ON (Modulated) button.
Make sure that deviation level read on the IFR correspond to model and bit rate in use
(see Table 8 - Typical Carrier Modulation). Re-adjust deviation as necessary referring to
the related Checklist (B for ParagonPD - page 26

6.4.4 Power Amplifier Module (T859 or T839)
6.4.4.1
6.4.4.2
Re-install the exciter module into the ParagonPD rack frame
Connect the Exciter module to the Power Amplifier.
Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD
style power meter, terminated with a 150W dummy load.
Forward and reverse power alarm set (control) are identified on the PA cover.
Power Amplifier Power Output
Key the transmitter on the exciter and adjust the PA output for 100W using front panel
power control. If power cannot be reached, refer to section 6.4.4.4 for T859 UHF model
or to Tait T839 service manual for T839 model. Cable loss should be included in the
reading.
Forward Power Alarm Level
1. Power up the PA and adjust front panel power control so that the output power is at the
alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA normally operates at 50W).
2. Adjust the forward power alarm set (T859: RV48 or T839: RV101) so that the forward
power alarm LED lights.
3. Adjust front panel power control (T859: RV63 or T839: RV109) for the normal operating power level
6.4.4.3
Reverse Power Alarm Level (Optional)
1. Power up the PA and adjust the front panel power control for the normal operating
power level.
2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust the reverse
power alarm set (T859: RV52 or T839: RV105) so that the reverse power alarm LED
lights.
Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad to the
PA output. This will result in a return loss of 6dB.

Adjust CV1 for maximum output.
Adjust CV8 for maximum output.
Adjust CV32 for maximum output.
Adjust CV51 and CV57 for maximum output.
Adjust CV34 and CV35 for maximum output.
Recheck all settings. The power output should exceed 110W.
For sets with serial numbers following 217262, adjust RV69 (driver power level)
until the output power drops to 110W.
12. For all units, adjust RV63 to reduce the power output to the required level (normally
100W).
6.4.4.5
Tait T859 Tuning for Best Efficiency
1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red
wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale)
2. While transmitting, monitor the current. It should remain under 22A.
3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply current, but do not exceed a maximum drop of 0.5A per control.
4. Check that the supply current is <22A for 100W output power.
Note:
These control settings are normally very close to minimum supply current. If the current
is reduced too far, maximum power output will drop and 2f rejection may degrade.

Deviation adjust
1. Using the RIS, press TX ON (Modulated) and record deviation level as read on the IFR.
2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD serial
number (e.g. abcd.bp1). “Save as” to another file name and keep it in case something goes
wrong while changing a parameter.
3. Locate the line labeled “Dev0 Par85=” and record the value beside the “=” sign. This is the
corresponding parameter value to the deviation read in step 1.
4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2
5. Change the value in the file, “Save as” using the BDLCPD serial number file name.
6. Run the RIS again and do a “Put From”. From the opened window, select the file that you
just made the change to and then press “OK”
7. Again, check deviation level while pressing TX ON (Modulated). If fine-tuning of Par90
value is still required, Edit the file again and re-do step 5 by changing directly the Par85
value by 1 or 2 up or down.
8. Re-check deviation level. If the level is now correct, press Stationreset to make the change
permanent.
