Chapter 2 Performance Tests
58502A Calibration (Option 010 Only)
2Use the terminal and serial port to send one of the following SCPI commands to incrementally adjust the EFC control signal to bring the oscillator frequency closer to 10 MHz:
DIAG:CAL:ROSC:EFC:ABS UP (or)
DIAG:CAL:ROSC:EFC:ABS DOWN
Where UP increases frequency and DOWN decreases frequency.
3As you approach the proper frequency, change the step size to smaller values by sending the following SCPI command:
DIAG:CAL:ROSC:EFC:ABS:STEP <value>
The default step size is 10,000. A recommended first reduction in size should be to 1,000.
4Continue to adjust UP or DOWN with finer increments until the frequency output is 10 MHz ± <1 ⋅ 10−9 (0.01 Hz).
5Record the date, EFC value, and frequency value on the Calibration recorded, located on page
6Return the EFC step size to its original value by sending the following SCPI command:
DIAG:CAL:ROSC:EFC:ABS:STEP 10000
This completes the 58502A calibration.
