BASICS Basic Description, Receiver Electronics The URB-100 receiver board consists of a: - Analog Part - Digital Part - Power / Alarm Part Analog Part P6 Beat J4 J2 J5 X6 J10 P10 X5 P8 J8 OFF P5 Video X7 J7 S1 WD R J3 Digital Part GND S2 J6 X18 P11 Video J9 R426 Volume GND J1 IN -) ON S3 Power (X1) DSP LF Relay (X3) Sync R224 Beatnote Gain NC Beat (- LF P7 IN RF-Gain P2 RLY NC NO GND OUT NC OUT P4/ RF (+ +) Mod GND Antenna (X2) GND GND P3/RF R112 Light (X4) P1/RF P9 Fuse Power / Alarm Part Receiver Board 1.1. Analog Part The first input stage amplifies the received RF signal. If this signal is too large, the gain of the first input stage can be reduced using jumper J4 (Narrow or Wide position). The next stage is a band-pass filter having a frequency range between 7.2 to 9.2 MHz. If necessary, the gain of the RF amplifier following the band-pass filter can be changed with potentiometer R112 (RF-Gain). An AGC is not built in, this gives a controlled RF amplification. The amplitude of the tag signal is pre-regulated by a fixed resistor. The DSP synchronization is done through "air", that is extracted from the received transmitter signal. A beat note circuit is implemented. This circuit is inhibiting spikes, radio transmitters and other signals with a very high Q factor. 1.2. Digital Part The analog tag signal is A / D converted and sampled. The DSP (40 MIPS) filters the demodulated LF signal and stores the result in a memory. It processes this data and if all alarm criteria are met, it triggers an alarm. DIL and rotary octal switches allow adjusting the software parameters and test positions. LUCATRON AG CH-8606 Greifensee, Switzerland Version 2 Page 3 URB-100 Tuning Guide 1.3. FEATURES Power / Alarm Part Power is supplied to the receiver electronics by applying 20-24 VDC or 18-20 VAC to the power supply/power filter part. The integrated filter is used to reduce any interference picked up on the incoming line from the power supply. An audible alarm (buzzer) is mounted on the filter part. Outputs for the antenna lamp and an external alarm are provided. The volume of the buzzer is adjustable with the Volume potentiometer (R426). A jumper (J10) on the filter part allows setting the buzzer for continuous or intermittent (optional) tone. The duration of the audible alarm is about 2 seconds. The duration of the alarm light is about 10 seconds. 2. Description of Features 2.1. Manually Adjustable RF Gain RF gain needs to be adjusted depending on the antenna type and the aisle width. In tuning mode S2=7 the RF level is shown on the scope and can be adjusted with (RF Gain) R112. With jumper J4 (RF attenuator) an additional attenuation of 10 dB can be selected. 2.2. Air Synchronization The sweep information is extracted by a PLL, which is factory adjusted. 2.3. Synchronous Demodulator The synchronous demodulator has a wide linear input range of 50 mVpp to 600 mVpp and high conversion gain. If the maximum level is exceeded, then the receiver is muted and the Inhibit (LED-4) status is on. 2.4. Beat Note Filter The beat note filter detects carrier signals that are crossing (beating) the system sweep. If the signal is too strong then DSP blanks it out. The sensitivity is adjustable with (Beat Note Gain) R224. The beat note filter is active when LED-5 is flashing. 2.5. Software Click Filter with Adaptive Slope Normally a demodulated tag signal is smooth. When the slewrate of a signal is too fast, this is an indication of induced noise and will be blanked out by the DSP. Some Hi-Q tags can trigger the filter. In that case it can be switched off with S3-5. Click filtering is active when LED-6 is flashing. 2.6. Software Spike Blanker The spike blanker counts the number of samples that are above a certain level. The level is about 50% of the actual alarm threshold. When a preset limit of counts is exceeded then the blocking acts, thus preventing false alarms in a noisy environment. The blanking is visible on LED-7. LUCATRON AG CH-8606 Greifensee, Switzerland Version 2 Page 4 URB-100 Tuning Guide 2.7. FEATURES Accept Counter The accept counter counts the number of consecutive sweeps detecting a tag. If the limit is reached in both sweeps, then an alarm is generated. The default is 24 sweeps, which gives approximated 300 ms response time. A faster response time can be selected with S3-3. 2.8. Threshold Calculation The threshold level is based on the signals plus noise averaged over the detection sweep. Under normal condition this would prevent from triggering an alarm because the threshold rises with increasing tag signal. The threshold is therefore delayed by approx. 1.5 seconds. This is roughly the time you have to trigger the alarm at full sensitivity. With the same time delay the system is back to full sensitivity again. 2.9. Alarm Threshold Margin Settings With switch S3-1 and S3-2 it is possible to adjust the alarm margin in 4 steps of 3 dB. The actual margin (peak signal to alarm threshold) is displayed on the LED Levelmeter. The actual alarm threshold level can be observed on the scope output. LUCATRON AG CH-8606 Greifensee, Switzerland Version 2 Page 5 URB-100 Tuning Guide TUNING 3. Tuning 3.1. Philosophy A system will be put into operation as follows: - First the TX (all) has to be prepared and then tuned. - Second the RX (s) has to be prepared and then tuned. - Third set the alarm conditions and make a final check. After this procedure the system is ready for operation. If an already installed system needs to be checked, the Quick Check procedure may give a first indication about the system status. An overview about the expert tuning and/or quick check procedures is given in a flow chart. 3.2. Recommended Tools The following instruments are necessary for tuning: - Multimeter - Battery-powered oscilloscope with two channels (minimum 20 MHz bandwidth). - 10:1 oscilloscope probes - Recommended: SMB cable (female / female, 1meter / 3 feet) plus BNC / SMB adapter (male / male). Radiall P / N R285215 and R191209. - Recommended: Sweep Span Meter (e.g. XRST-1 crosspoint.nl) or equal. The SSM displays the minimum, maximum, center and the sweep frequency of a swept RF signal. 3.3. Receiver Preparatory Steps 3.3.1. Preparation • Remove power from the RX board by removing the PWR connector at socket X2. • Verify the default jumper J1 to J9 settings (J4 and J6 are under the shield). See table and layout.

QUICK CHECK Quick Check 3.6.1. Basics For a Quick Check, the Rotary switch (0 to F9) can be turned to different Test positions. The LED “Test” indicates that the Rotary switch is not anymore in the standard (0) position. The three yellow Indicator LED’s are used as a Levelmeter. The Quick Check Procedure is no full replacement of the real tuning as described in chapters 3.4 – 3.5. Especially the proper setting of the beat note level needs to be done with the help of an oscilloscope. 3.6.2. RF-Gain Check • Set Rotary switch to position 7 (RF-Gain Check / Adjustment). The Test LED is lit. Let all DIL switches in their ON position. ON DIL S3 Rotary Switch S2 OFF S3-6 S3-5 S3-4 S3-3 S3-2 S3-1 • Turn the RF-Gain potentiometer R112 until only the Center LED of the Levelmeter is ON.
