Option 106 Microwave Channel Frequency Calibration
The following procedure should be performed when Option 106 (6 GHz
Microwave channel) with any Option 106 firmware revision other than
FW Rev 27 is installed as Channel 2 in a 53210A or Channel 3 in a
53220A or 53230A. See Chapter 6 “Backdating” for the procedure to
calibrate Option 106 with FW Rev 27. (Refer to “Determine the
Counter Firmware Version” on page 106.)
1 First, run the counter Self-Test as described under “Performing
The Counter Self-Test” on page 159. A successful self-test
procedure verifies that the counter is operational and ready for
calibration.
2 Unlock the counter by performing the procedure “To Unlock The
Counter For Calibration:” on page 103. Key sequence:
[Utility] / (Cal AutoCal) / enter <code> / (Unlock Cal)
3 Set up an external microwave frequency source for a 500 MHz
sine wave at -27 dBm. If the source has an ‘output enable’ feature,
turn it OFF at first (for the zero-calibration procedure).
4 Connect the microwave frequency source to Channel 3 on the
counter front panel. (Channel 2 for a 53210A.) See Figure 2-7.
