12.7 Procedures (CH1): Frequency Amplitude (Source)
Do the procedure as follows:
Note:
The procedure that follows calibrates the “mark” value of the square wave frequency
output. The “space” value is fixed and is approximately
-
120
mV.
1. Connect the applicable calibration equipment. Refer to Table
1.
2. Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
3. Set up the equipment as follows:
•
Source frequency = 0 (for DC output)
•
Waveform = Square
4. Use the calibration menu (see Section
12.1) to do a two-point frequency source calibration.
•
Point
1 = 0.2
V
•
Point
2 = 20
V
5. Check the calibration is correct:
a. Set up the equipment as follows:
•
Source frequency = 0 (for DC output)
•
Waveform = Square
b. Apply the amplitude values that are applicable to the calibration. Refer to Table
10.
c. Check the error is within limits. Refer to Table
10.
12.8 Procedures (CH1): Resistance (Measure)
Do the procedure as follows:
1. Connect the applicable calibration equipment. Refer to Table
1.
2. Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
3. Use the calibration menu (see Section
12.1) to do a two-point resistance measure
calibration.
a. Range: 0

Ω
•
Nominal zero ohms - make a 4-wire connection to the 0
Ω.
