TEST PROCEDURES
Each test procedure relies on the UUT being set to its power-up conditions. Reset the UUT after
each test procedure by setting:
Store/Recall Address 999
Recall
At the end of this chapter are a set of results tables which give all the test points for each of the
tests. These tables should be photocopied and used to record the results of all the measurements
taken.
RF output
Specification
Range
−137 dBm to +25 dBm (+19 dBm above 1.2 GHz).
When AM is selected, the maximum RF output level decreases linearly with increasing
AM depths to +19 dBm (+13 dBm above 1.2 GHz) at 99% depth.
Accuracy
VSWR
For output levels less than −5 dBm output VSWR is less than 1.3:1 for carrier
frequencies up to 1.2 GHz and less than 1.5:1 for carrier frequencies up to 2.4 GHz.
Output impedance
50 Ω SMA female connector to MIL 390123D.
