Four major circuit boards per• form these functions: RF Preselector A1, FM Demodulator A3, FM Stereo A4, and Display Driver A6. The block diagram, Figure 6• l, is located in Section 6 of this manual. RF input from either transmitter or antenna enters the 884 rear panel and is routed to RF Preselector A 1. Here the signal is padded through the attenuated circuit to a balanced mixer. The 900 kHz IF signal is sent to a low pass filter. This IF is then routed to the Demodulator Board A3. . FM Demodulator A3 receives the 900 kHz IF, demodulates the signal, and delivers a pulsed output that is filtered and amplified. The resulting signal is filtered and routed to the FM Stereo Board. On A4 the composite signal is filtered and returned to A3 and to the front panel monitors and test outputs. Separation adjust is also performed on A4. Positive and negative modulation are used to drive the front panel PEAK flashers on A6, the Display Driver. Each modulation peak is compared in a peak detector to a voltage olr tained from a constant current source by means of resistances selected by pushbutton switches on the· PEAK MODULATION flashers. The pulse outputs produced by the peak detect0rs when modulation exceeds user preset values are applied to the front panel LED flashers, which light for approximately 2 seconds.. 4.2 RF Preselector Al (Figure 6-3) The RF input to the monitor comes from the sampling point of the transmitter as a high; level signal or from an antenna. The high input level enters the 884 through the rear panel RF INPUT HI LEVEL (50 ohm) connector J7. The signal is fed through the adjustable at• tenuator HI LEVEL RF INPUT SET R2 on the rear panel. This high level input signal is adjusted for a constant level and goes to the AM NOISE detector, which is routed to the front panel TOTAL MODULATION/TEST meter. The high level also lights the rear panel HI LEVEL RF INPUT SET LED (21) when the ~F level adjust is correct. The RF signal goes to the ANTENNA INPUT jack (24 ). 4-1 STEAM POWERED RADIO.COM Model 884 When an antenna signal is fed to the ANfENNA INPUT, JS, it is routed to Zl and mixed with the frequency synthesizer L.O. (local oscillator) and becomes a 10.7 MHz IF. This IF is fed to linear phase filter FLl and then the lF amplifier Ul. At Ul, the level detectors detect the antenna level as the de component. When detected, the antenna level is fed to US, the mute detector. The factory sets the mute level for 40 µ Y RF input. When the mute level is less than the factory•set level, US shuts off the demodulator. This level also goes to the rear panel terminal strip, TB 2. The IF from Ul is also fed to Tl, the IF transformer, and then to U17, the balanced mixer. The 10.7 MHz signal mixes with the second LO., 10 MHz, from the timebase crystal oscillator. The mixed signal goes to the low pass filter which looks for the 700 kHz second IF. This 700 kHz is routed to the Q7 and Q8 switch and fed to A3, the FM Demodulator Board. The 10 MHz timebase is crystal-controlled oscillator Yl and its associated components. It is the reference for the PLL frequency synthesizer and is also the second LO. 4.3 FM Demodulator A3 (Figure 6-5) The 900 kHz IF signal which is applied to the FM Demodulator Board A3 through a relay to a pulse counting FM demodulator circuit. The limiting amplifier, Ul, is driven into saturation to provide limiting. U2 is a one-shot multivibrator acting as a pulse averaging discriminator. It delivers a pulsed output whose frequency is the same as the IF but with a fixed pulse width. The duty cycle in the output pulse train varies with the modulation and the audio is recovered by passing the discriminator output through a low pass filter. Transistors Ql thru Q4 make up the clamping circuit. The low pass filter consists of 1.2 and L3 and amplifier U7. This circuit provides a flat response to 100 kHz and linear phase in order to give good stereo measurements. The fre• quency response rolls off after 100 kHz to eliminate any resiual 900 kHz. Amplifier UlO raises the audio level to 1 Vrms. monitor calibration circuit consists of U3 thru U6. The 358 kHz output of the timebase is divided down to 4.48 kHz, which is then used to gate the 200 kHz on and off at a 4.48 kHz rate. This simulates a 100% modulated input. When the front panel METER CAL switch is depressed, this calibration signal is fed into limiting amplifier Ul and discriminator U2 in place of the 900 kHz IF. After passing through a 7.5 kHz calibration low pass filter, it is amplified by U8, which is adjusted by CAL LEVEL ADJUST R29 to give a 100% reading on the TOTAL MODULATION/fEST meter. The signal can also be used to check meter and flasher calibration. The circuit is very stable and can be ·used to correct drifts in the one-shot discriminator U2 and the meter amplifiers.

I General Descript ion The TIT Model 884 FM Stereo Modulation Monitor is a high quality, compact, and comprehensive monitor used to maintain desired modulation levels and FM broadcast quality standards. Contained in one 7-inch, rack-mounted package ·is a single-channel, low level RF preselector, an FM monitor, a stereo baseband monitor, and peak detectors. The user can operate the Model 884 at the transmitter site, off-the-air at the studio, or can monitor composite signals from a stereo generator or composite STL when checking only portions of the broadcast chain. Two meters permit you to observe the right channel audio and a user-selected parameter simultaneously. The TOTAL MODULATION meter doubles as the test meter. Pushbutton switches select monitor mode and meter sensitivity, thus allowing a variety of measurements to be made, including the total composite baseband signal, L + R or L-R subchannels, and left or righ t channels. A front panel switch selects positive or negative modulation metering, and another switch selects whether de-emphasis is switched in or out. The Model 884's flex ibility enables station personnel to measure virtually any parameter of importance to FM ste reo broadcasting. These measurements include frequency response, stereo separation, main-to-sub and sub-to-main crosstalk, 19 kHz pilot level, 38 kHz subcarrier suppression, and even AM synchronous noise on the main carrier. 'fo enable a station to maintai n the maximum permissible modulation levels, the Model 884 includes LEDs that light when positive or negative peaks exceed a user-set threshold of modulation set via pushbutton switches. These LEDs are driven by TFf's exclusive Peak Modulation Duration Differentiator circuit (PMDD, patent pending), which distinguishes true modulation peaks from erroneous peaks resulting from ti lt, overshoot and ringing, or multipath. A fron t panel BNC Test outpu t allows convenient connection to external test equipment such as an oscilloscope (for stereo generator setup of flat baseline and pilot phase). Gn the rear panel, balanced left and right channel audio outputs are provided, and a jumper selects whether the de-emphasis is enabled.

ANT LEVEL, terminals 9 and 10 3.4 Measurements The Model 884 performs a variety of measurements. This section discusses the procedures required for making those measurements. 3.4.1 Main Channel Modulation (L + R) Press the L + R function switch and the O dB (100%) attenuation switch. The TOTAL MODULATION(fEST meter will indicate the main channel modulation directly in percent. A fully modulated left or right channel only signal will indicate 45% on the meter; a fully modulated L = R signal will indicate 90%; and a fully modulated L = -R signal will indicate 0. 3.4.2 Stereo Subchannel Modulation Press the L - R function switcp and the O dB (100%) attenuation switch. The TOTAL MODULATION(fEST meter will indicate the stereo subchannel modulation directly in percent. A fully modulated left or right channel only signal will indicate 45% on the meter; a fully modulated L = -R signal will indicate 90%; and a fully modulated L = R signal will indicate 0. 3.4.3 Pilot Carrier Modulation Press the 19 kHz function switch and the -20 dB (10%) attenuation switch. The TOTAL MODULATION(fEST meter will indicate the pilot modulation level, with 100% meter reading indicating 10% modulation. Correct pilot modulation level is between 8% a nd 10%. It can be measured when program modulation is present; slight "bouncing" of the meter needle is normal under this condition. 3.4.4 38 kHz Subcarrier Suppression To measure 38 kHz subcarrier suppression, perform the following: a. Apply a modulating signal between 5 kHz and 15 kHz to the left channel of the stereo generator and adjust its level to indicate 90% on the TOTAL MODULATION/fEST meter. b. Press the 38 KHz function switch. c. With the TOTAL MOD/fEST METER attenuation switches, select an attenuation that provides a usable reading on the TOTAL MODULATIONffEST meter. The 38 kHz subcarrier suppression is the algebraic sum 3-5 STEAM POWERED RADIO.COM Modcl884 of the meter reading and the attenuation inserted. For example, a meter reading of -2 dB with the -50 dB meter attenuation switch depressed denotes a 38 kHz subcarrier suppression of 52 dB below 100% modulation. 3.4.S Stereo Separation Left and right channel modulated signals can be measured independently on the Model 884. The following paragraphs describe the procedures used to measure these signals. / 3.4.5.1 Left Channel Modulated Signal To measure the "Left into Right" channel separation, perform the following: a. Apply a modulating signal between 50 Hz and 15 kHz to the left channel and adjust its level to indicate 90% on the TOTAL MODULATION/fEST meter. h. Press the R function switch. c. With the TOTAL MOD/fEST METER attenuation switches, select an attenuation that provides a usable reading on the TOTAL MODULATION(TEST meter. The channel separation is the algebraic sum of the meter reading and the attenuation inserted, less approximately 1 dB (0.915 dB) to account for the 90% left channel modulation level. For example, a meter reading of -2 dB with the 1%/-40 dB meter attenuation switch depressed denotes a stereo channel separation of 41 dB. 3.4.5.2 Right Channel Modulated Signal To measure the "Right into Left" channel separation, perform the following: a. Press the R function switch. b. Press the OdB (100%) TOTAL MOD{fEST METER attenuation switch. c. Apply a modulating signal between 50 Hz and 15 kHz to the right , hannel and adjust its level to indicate 90% on the TOTAL MODULATIONffEST meter. d. Press the L function switch. e. With the TOTAL MOD/fEST METER attenuation switches, select an attenuation that provides a usable reading on the TOTAL MODULATION/fEST meter. The channel separation is the algebraic sum of the 3-6 STEAM POWERED RADIO.COM Model 884 meter readin g and the attenu ation insert ed, less 1 dB to accou nt for the 90% right chann el modu lation level. 3.4.6 Main Chann el to Subch annel Cross talk To measu re main chann el to subch annel crosstalk, perfor m the follow ing: a. Press the TOTA L MOD (fEST METE R L + R functi on switch and the 0 dB (100% ) attenu ation switch. b.

With the TOTA L MOD ffEST METE R attenu ation switches, select an attenua tion that provid es a usable readin g on the TOTA L MOD ULATION (fEST meter . The crosst alk measu red is the algebr aic sum of the select ed attenu ation and the meter readin g, less 1 dB to accou nt for the 90% modu lation setting . 3.4.7 Subch annel to Main Chann el Cross talk To measu re subch annel to main chann el crosstalk, perfor m the follow ing: a. Press the L - R function switch and the 0 dB (100% ) TOTA L MOD /fEST METE R attenu ation switch. b. Apply an L - R modu lating signal to the stereo gener ator and adjust the level for a 90% readin g on the TOTA L MOD ULAT ION{ fEST meter . c. Press the L + R functi on switch. d. With the TOTAL MOD /fEST METE R attenu ation switches, select an attenuat ion that provid es a usable readin g on the TOTA L MOD ULATION (fEST meter . The crosst alk measu red is the algebr aic sum of the select ed attenu ation and the meter reading, less 1 dB to acco,• nt for the 90% modu lation setti ng. 3.4.8 FM Noise To measu re FM noise, perfor m the following: a. Apply an L + R modu lating signal to the transm itter under test and adjust the level for a 90% readin g on the TOTAL MOD ULATION /fEST meter . 3-7 STEAM POWERED RADIO.COM Model 884 b. Turn off all transmitter modulation. c. Press the TOTAL MOD (total modulation) switch. d. With the TOTAL MOD!fEST METER attenuation switches, select an attenuation that provides a usable reading on the TOTAL MODULATION(fEST meter. The algebraic sum of the selected attenuation and the meter reading is the FM signal-to-noise ratio. NOTE If a de-emphasized reading is required, the DE-EMPH function switch must be depressed. 3.4.9 Distortion To measure distortion, perform the following: a. Apply a modulating signal to the desired audio channel. b. Connect a distortion analyzer to the front panel TEST OUTPUT and select the Lor R switch. 3.4.10 Pilot Frequency To measure the pilot frequency, perform the following: a. Connect a frequency counter to the TEST OUTPUT jack on the 884 front panel and depress the 19 KHz function switch. b. The transmitted pilot frequency is read directly on the counter. 3.4.11 Peak Modulation Positive and negative peak modulation is read directly on the front panel using the PEAK MODULATION flashers and switches. To read peak modulation, perform the following: a. Calibrate the % PEAK flashers so that the lights just come on in the CAL mode. For peak modulation calibration, see Section 5, Paragraph 5.1.2 of this manual. 3-8 STEAM POWERED RADIO.COM Mo -\ PAU NO NOll[NCUfUU H DUC~1'1ION -F,-- IPlClftC&UONS UNllll 01NIIIW1SI N011D j i INAClt _ __ .... .,1•• @ 884 STEAM POWERED RADIO.COM • · - - - - .. 7 I *.--- All"'UI• l(CIMAI.• . l l ' U C l • - -- - . ..,;_ . 6_ 5 4 .. .· - 5004-0$ -- IIXTAIU ,I :IMC XJ'JfJO.:.•.UtA :J t.•1,tAUl l 1R SAN1~ (lAAA CA ~S.,-~1 flOIJ• ntx 9,01.lN 1r.J ltfJ I✓=' ,_.,1} A MODEL 884FRONT AND REAR ILLUSTRATION _ luaflCI IOUGl a IOMH1 01VIO£A JrTAl 09C. l-fl Pl.OT ----o SlkHa - 1\ l_,.
