For models with external pulse modulation:
a.
Press
Modulation
to open the Modulation menu.
b.
Press
Pulse
, then select external pulse mode by pressing
Internal/External
, if required.
c.
Turn the pulse mode on by pressing
On/Off
.
d.
Repeat steps 2c through 6.
Power Level Accuracy (
–50 dBm)
Power level accuracy for power levels of –50 dBm and above are tested by stepping the output power level down
in 5 dB increments from its maximum rated power level and measuring the output power level using a power
meter at each step. For all power level measurements above –50 dBm, connect the equipment as shown in
1.
Set up the power meter as follows:
a.
Reset the power meter by pressing:
System
| Setup | -more- | PRESET | RESET
b.
Configure the power meter to perform power measurements by pressing:
Sensor
| Setup | MODE | Default
c.
Configure the power sensor’s calibration factor source by pressing:
Sensor
| CalFactor | SOURCE | V/GHz
, until V/GHZ is displayed.
d.
Setup the minimum V/GHz range by pressing:
Setup | Start F
e.
Enter the minimum frequency of the MG under test or minimum of the power meter.
f.
Setup the maximum V/GHz range by pressing:
Setup | Stop F
g.
Enter the maximum frequency of the MG under test or maximum of the power meter.
h.
Press any hard key to begin the measurement.
2.
Set up the MG362x1A as follows:
a.
Reset the instrument by pressing
SYSTEM
, then
Reset
. After reset, the CW menu is displayed.
b.
Press
FREQUENCY
to open the current frequency parameter for editing.
c.
Set F1 to the CW frequency indicated in the test record.
d.
Press
LEVEL
to open the current power level parameter for editing.
e.
Set L1 to the power level indicated in the test record.
3.
Measure the output power level with the power meter and record the reading in the test record.
4.
On the MG362x1A, use the cursor control key (Arrow keys) to decrement L1 to the next test power level
in the test record. Measure and record the power meter reading in the test record.
5.
Repeat step 4 for each of the test power levels listed in the test record (down to –50 dBm) for the current
CW frequency.
6.
Repeat steps 2b through 5 for all CW frequencies listed in the test record.
