If you are able to read the error message(s), consult
page 174 for what to do after receiving a specific calibration error message.
Summary of Option 115 microwave calibration procedure:
– Input signal: This should be a clean sine wave at each frequency and power
level, driving 50

termination.
– Timebase: Any external timebase you provide is ignored during calibration.
– Verify signal input connections and source output is ON.
– Procedure: From the front-panel, the following key strokes initiate the
microwave frequency channel calibration:
[Utility] / (Cal AutoCal) / (Perform Cal) / (Cal Step uWave) / enter (Input Freq)
<frequency>
[Utility] / (Cal AutoCal) / (Perform Cal) / (Cal Step uWave) / enter (Input Power) <power>
/ (Perform Cal Step)
Summary of Option 115 remote microwave calibration:
– Set timeout for PC to be greater than 20 seconds.
– Unlock security:
CALibration:SECurity:STATe OFF, <code>
– Read security state:
CALibration:SECurity:STATe?
– 0 means OFF or unlocked.
– Send zero-calibration command (one-time only):
– Use: “
CALibration:LEVel3? 0,0
” for 53220A/53230A.
– Use: “
CALibration:LEVel2? 0,0
” for 53210A.
– Retrieve query result:
– 0 indicates the calibration PASSED.
– Any value other than 0 indicates calibration FAILED.
NOTE
If you do not have a remote computer available (requires a LAN, USB or GPIB
interface) or are not proficient at programming, contact the nearest Keysight
Service Center for information and help on sending the counter to Keysight for
repair and/or calibration.
