CAVU 2100TM
Multi-Mode Digital Radio (MDR) Power Supply Test Procedures ver 2.0
10-29-2018
General Power Supply Info:
Primary Power
• AC Voltage 120 V (±10%), 60 Hz (±3 Hz)
• AC Current o 15W RF Power Output 4.0 Amps maximum o 50W RF Power Output 8.0 Amps maximum allowed
• DC Voltage 24 V (-10/+20%)
• DC Current o 15W RF Power Output 10.0 Amps maximum o 50W RF Power Output 20.0 Amps maximum allowed
Real Time measured values during operation were seen to be as follows:
The 24v UNREG supply input was measured at 1.3A min/9.1A max.
The basic function of this board is:
• To provide DC voltage ( +5, +15 and -15V dc) to the DSP board in the system.
• It also serves to monitor the AC source and determine if there is need to switch over to an external 24v DC power supply. ( Dual 24vdc supplies, one internal & one external)
• Provide pass through connection for the unregulated 24VDC supply which is supplied to the PA.
Based on FAA measured values on an operational system, the following is a summation of the Output power budget for the board:
• P5 Output connector ( +15/-15 & 5vdc supplies) = 1300mA
• P4 Output connector (+15/-15 & 5vdc supplies, 24vdc unreg) 2200mA
• P3 Output connector( 24vdc unreg) 8600mA
• P1 & P2 Input sources ( Unreg 24, & external 24vdc)

Figure 14-1. CAVU-2100 MDR TX / RX Temperature Chamber Testing Profile
Mr. Ed Lugo is considered the AJW-14 expert with the NETS building temperature chamber. He created a script file to comply with figure 14-1, and also programmed the profile into the chamber.
Testing commenced on 06/06/2016 and concluded on 6/13/2016.
The following is the log notes of the testing and radios’ setup:
TESTING LOG
1. 6/6/2016: The HP8920A Test Set was utilized for TX setup, and using 1004 Hz
@ -8 dBm for tone modulation. Also utilized was dummy load (Bird model 8135, 50 ohm, 150 W).
CAVU-2100 Rev0 Power Supply Temperature Chamber Testing
P a g e | 3
a. MDR TX was setup with 136.975 MHz, 51.9W, and 99% ± 1% as per Paul
Riley. The power and modulation level represents design limits.
b. Testing commenced at 4:00 PM.
2. 6/7/2016: Using 26 VDC excitation (power) for the MDR TX, measured current at
+50 °C: was 8.4 A. AT -10 °C was at 8.1A.
3. 6/8/2016: All looks normal
4. 6/9/2016: All looks normal.
a. @50 °C, measured 8.3A (AC power) and 8.4 A (DC power).
b. The MDR TX was the only device to be originally tested. This was the original decision, due to it drawing much greater operational current than the RX. This testing was originally planned to only test the Rev0 power supply assembly in an operational radio under worst case temperature and operational conditions
c. As per Paul Riley: at 2:40 PM the testing was halted to add the MDR RX into the chamber. To test RX required stopping TX modulation due to
HP8920A limitation.
i. Set TX to 50 W unmodulated. Set RX RF level to -71 dBm with
90% modulation.
ii. Set temperature chamber to 50 °C.
iii. Planned to run this test from Thursday at 5:50 PM to Monday morning (6/13/2016).
5. 6/13/2016: Found TX in ‘recovery mode’. Cycled power and successfully keyed the TX. Informed Ben Lamb and requested TX log review.
a. RX sensitivity measurement performed manually while chamber was hot
(50 °C).
i. RX sensitivity check: -76.0 dBm for SNR = 10 dB.
ii. Adjusted chamber to 25 °C. There was no change in RX sensitivity.
iii. TX log showed PA control board temperature alarm at over 90 °C.
iv. TX power measured 51.5 W.

v. Ran chamber testing.
1. TX again had over temperature alarm after about 50 minutes.
2. Reduced TX to 30.8 W and 80.2% modulation. Ran chamber testing again at 3:48 PM.
6. 6/13/2016: TX again had over temperature alarm after 42 minutes from previous start.
a. Testing concluded due to having chamber for a solid week and another person in queue to use the chamber.
CONCLUSIONS
1. The TX experienced over temperature alarms due to its top surface ventilation holes being covered by the introduction of the RX into the chamber. The RX was sat on top of the TX. The TX top surface ventilation passes through the top and out the cavity filter ventilation holes. Being covered by the RX prevented normal ventilation and caused the TX interior temperature to become excessive.
b. Back at the OKCET lab, the TX was keyed at 50 W and allowed to remain in this mode for a day. It behaved normally.
2. The OKCET Rev0 power supply assembly performed without incident and as designed.

What follows is the raw data acquired using the v4.0 of the OKCET CommApp (E_App).
Test equipment and configuration is driven within the CommApp. Test results are automatically generated from CommApp. The test subjects were a CAVU-2100 MDR transmitter (TX) and a MDR receiver (RX). Both were tested with the original ITT power supply and the OKCET Rev1 power supply assembly without / with Stabilant 22A applied to all accessible connectors, especially the RF connector(s).
The following is a list of the test criteria:
a. Each radio was tested at three frequencies (118.000 MHz, 127.975 MHz, and 136.975 MHz).
b. Each radio was tested at three AC power voltage levels (90.0 VAC, 120.0 VAC, and 132.0 VAC) and threes DC voltage levels (21.6 VDC, 24.0 VDC, and 26.4 VDC). All voltages represent minimum / maximum specified operating levels or worst case for the actual internal power supply (only
90.0 VAC).
c. Each radio was tested using the:
i. Original ITT power supply.
ii. OKCET Rev1 power supply.
iii. OKCET Rev1 power supply with all accessible connectors (especially the RF connectors) dressed with Stabilant 22A.
Stabilant 22A provides the signal performance equivalent of a high quality solder connection between connector mating surfaces of physical connectors. Its description is provided within attachment 16.

2. What follows is a spreadsheet showing all data results acquired from the CommApp against the test subjects. The spreadsheet shows the above data in a more reasonable view to permit easier understanding.
The following is a list of the test criteria:
a. Each radio was tested at three frequencies (118.000 MHz, 127.975 MHz, and 136.975 MHz).
b. Each radio was tested at three AC power voltage levels (90.0 VAC, 120.0 VAC, and 132.0 VAC) and threes DC voltage levels (21.6 VDC, 24.0 VDC, and 26.4 VDC). All voltages represent minimum / maximum specified operating levels or worst case for the actual internal power supply (only
90.0 VAC).
c. Each radio was tested using the:
i. Original ITT power supply.
ii. OKCET Rev1 power supply.
iii. OKCET Rev1 power supply with all accessible connectors (especially the RF connectors) dressed with Stabilant 22A.
Stabilant 22A provides the signal performance equivalent of a high quality solder connection between connector mating surfaces of physical connectors. Its description is provided within attachment 16.

d. From Table 1 below, for each radio type (TX or RX):
i. The set point for each parameter is provided as a separate table for each measured parameter and is located above the respective table showing the actual measured values for each parameter.
ii. The measured parameters’ table for each radio type shows the values automatically obtained from Comm Application v4.0.
iii. Also shown in each radio type’s measured data are columns showing the percentage change of the immediate value left of the column as compared with the radio using the original ITT power supply, with frequency and radio excitation voltage level being held constant. This method provides a direct comparison based on changing the actual power supply and also when using the Stabilant 22A product.
e. Conclusions from Table 1.
i. Occasionally measurements were reported which are believed to be within equipment tolerances, but may slightly skew perceptions of an improvement or not.
ii. In general, the OKCET Rev1 power supply provides equivalent or improved performance compared to the ITT power supply.
iii. In general, the OKCET Rev1 power supply with the Stabilant 22A product applied to all accessible connectors provides additional performance improvement than without the Stabilant applied.

1. Ensure both R3 and R4 are fully CW.
3. Adjust AC voltage level = 104.5Vrms.
4. Adjust R3 CCW so K1 (AC PWR RLY) 'just' turns off
(@6.5 - 6.8 VDC). The radio will deenergize.
6. Check 104.5V trip point by slowly adjusting AC from
105V to 104.5V. If adjustment is needed, redo associated steps.
Trip Select: 85VAC (LOW)

12. Set DC power supply = 29.6 VDC.
8. Adjust variac AC output voltage level = 85.0 Vrms.
10. Adjust R4 CCW so K1 (AC PWR RLY) 'just' turns off (6.5 - 6.8 VDC).
BenchTop: UNREG24TX/RX Relay (K1) Trip Adjustment and DC Relay K2 Check:
9. Measure TP4 wrt TP5 (VDC).
2. Shunt P11-1 to P11-2 to select 85 VAC Trip .
1. Ensure both R3 and R4 are fully CW.
13. Adjust AC voltage level = 104.5 Vrms.
15. Adjust R3 CCW so K1 (AC PWR RLY) 'just' turns off (6.5 - 6.8 VDC).
17. Check both 85V (shunt P11-1 to 2) and 108V (remove shunt) trip points and hysteresis. If adjustment is needed, redo associated steps.
22. Apply loctite to both R4 and R3.
3. Set DC power supply (emulate VUNREG) = 23.6 VDC.
4. Attach DC power to P1 (P1-1 = Gnd, P1-2 or P1-4 = 23.6 VDC).
5. Shunt P7-2 to P7-3 (UNREG Relay Gnd enable).
6. Shunt P9-2 to P9-3 (DC Relay Gnd enable).
7. Connect variac output to AC Monitor Cable.
11. Confirm hysteresis (@2.0 VAC greater and then trip level.
14. Remove shunt from P11-1 to P11-2.
16. Confirm hysteresis (@2.5 to 3.5 VAC greater) and then trip level.
In Radio: UNREG24TX/RX Relay (K1) Trip Adjustment:
2. Install power supply assembly and AC monitor cable.
5. Confirm hysteresis (@2.5 - 3.5 VAC greater) and then trip level.
18. Perform EXT DC check. Move VDC from P1-2 (or -4) to P2-2.
19. Lower VDC to about 20.6 VDC or until DC power relay (K2) turns OFF.
20. Increase VDC about 1.0 VDC to check hysteresis (relay ON).
21. Remove all power sources and all shunts.
