Option 27 Scan Calibration
1.
Set the UUT to 1 GHz, 0.0 dBm. Select VAR ATTN: ON.
2.
Using a Giga-tronics 8540 power meter (or equivalent), measure the RF output power of
the UUT (see the 8540 frequency value equal to the frequency being measured). Verify a
reading of 0.0 dBm
±
2 dB.
3.
Select relative mode on the 8540 power meter. Turn the UUT’s power off. Zero the
power meter, then turn the UUT’s power on.
4.
Set VAR ATTN to -50 dB. Adjust R65 on the A7 PC board for a reading of -50.0 dBm
(
±
2 dB).
5.
Set VAR ATTN to -10 dB. Adjust R9 on the A7 PC board for a reading of -10.0 dBm
(
±
2 dB).
6.
Repeat steps 4 and 5 until both readings are within specification.
7.
Step the VAR ATTEN depth from 0 to -60 dB in 10 dB steps, and verify that all
readings are within specification.
☛
NOTE: The power meter must be accurate to -65 dBm. Zeroing the power meter
every two minutes with the UUT’s RF power off is recommended.
8.
With the UUT’s frequency set to 5, 10, and 20 GHz, verify that readings at -10 dB and
-50 dB are within specification.
