b.
Set F1 to the LO CW frequency indicated in the test record.
c.
Ensure
Set L1
is set to +13 dB
8.
Set up the measuring receiver as follows:
a.
Press the
Freq
key and enter the CW frequency listed in the test record.
b.
Press the
Offset
key, select the offset valve, enter 0.
c.
Read the measured value and calculate the line and mixer loss offset as follows:
d.
(Test record reading at –40 dBm for the current test frequency) – Receiver Reading = Offset
e.
The offset value should be a positive number.
f.
Press the
Offset
key and select
Offset On
.
g.
Select
Offset Value
and enter the offset value that was calculated above. The displayed
reading on the measuring receiver should be the test record reading at –40 dBm for the
current test frequency. If not, repeat steps b through e.
9.
On the MG3702xA, set L0 to the power level indicated in the test record starting with –55 dBm.
10.
Measure the relative output power level and record the reading in the test records.
11.
Repeat
and
for each of the test power levels listed in the test record for the current
CW frequency.
12.
through
for all CW frequencies listed in the test record.
Note
When measuring frequencies above 2400 MHz, the measuring receiver, LO, and MG3702xA, should
be connected to the mixer. The measuring receiver should be set to measure 8.51 MHz.
Note
When making power level changes greater than 15 dB, the first measurement should be thrown out
to allow for the measuring receiver to auto range.
Note
Depending on options and model numbers not all levels in the test records are tested. The lowest
level measured is 100 dB below the maximum leveled power. In some cases measurement at or
below -75 dBm is not required. Refer to the Technical Data Sheet for maximum leveled power
specification and subtract 100 dB. This will determine the lowest value to measure.
