Measure DC voltage at radio board TP1
+0.6 to +2 VDC
(+1.3)
No DC power in at battery contacts
Wait until transmitter completely powers down (approx. 4 sec)
Apply +3.0VDC, 500mA current limit in at battery contact J8 (J9 is circuit common)
Hold Power button for 3 seconds (make sure unit come on).
Measure carrier signal power to be sure the VCO starts on power up at selected
carrier frequency
≥
+10 dBm
Carrier signal power adjustments & spectral purity measurements
Momentarily connect audio board TP22 to J5 pin 4 (enter Set-up mode)
Note
Entering Set-up mode is not necessary if the Alternate Method is exercised.
Note
Power Measurement are made with the output of the DUT connected directly to the power measuring device to
ensure an accurate as possible measurement.
Using the test key pad navigate to the "PwrCal" screen
Note
This sets the DUT to 50mW carrier power at the Mid carrier frequency, from here pressing the UP or DWN buttons
adjusts carrier power. Pressing MENU/SEL button once will move to the lowest carrier freq. UP and DWN buttons
adjusts carrier power. Press MENU/SEL again moves to the highest frequency, UP and DWN buttons adjusts carrier
power. Pressing MENU/SEL once more moves to 100mW at the Mid carrier frequency and the pattern continues.
Measure current draw
Repeat this process until all 6 carrier signal power points have been adjusted and double checked after the last
adjustment has been made
