General Calibration/Adjustment Procedure

The adjustment procedures described in in this appendix use the CALibrate subsystem commands to generate and set internal calibration constants. This general SCPI command procedure is the same for all calibration setups.

1.Unsecure the function generator See “Calibration Security Code” on page 174. Use the following SCPI command

CAL:SEC:STAT OFF,<sec_code> set secure state off; enable cal

2. Send the Calibration Setup. Use the following SCPI commands:

CALibrate:SETup <setup_number> configures the output

3.Use the reccomended instrument to measure the actual output of the Agilent E1441A

4.Send the measured value to the Agilent E1441A with the CAL:VALue command. The function generator will correct its output and store the new calibration constant. Use the following SCPI command:

CAL:VALue <measured_val> set the calibration value

5. Initiate the calibration process. Use the command:

CAL?	performs calibration and
	updates the cal constant

<read the CAL? response; 0 = cal OK, 1 = cal error>

6. Repeat steps 2 through 5 for each calibration setup.

Calibration Example

The following example command sequence demonstrates making the

Frequency and Burst Rate adjustments.

/* Adjust main frequency generator */ CAL:SEC:STAT OFF,<sec_code> CALibrate:SETup 00

*OPC?

<enter "1" from *opc? when complete>

<read the	frequency counter value>
CAL:VALue	<counter_value>	set calibration value
CAL?		perform calibration
<read the	CAL? response; "0"=cal OK, "1"=cal error>
/* Adjust	burst rate timing, pulse output */
CALibrate:SETup 01		configures burst rate cal
		(setup 01)
*OPC?		wait for output to stabilize
<enter "1" from *opc? when complete>
<read the	frequency counter value>
CAL:VALue	<counter_value>	set calibration value
CAL?		perform calibration
