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 12 - 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 12 - 10.
c. Check the error is within limits. Refer to Table 12 - 10.
12.8 Procedures (CH1): Resistance (Measure)
Do the procedure as follows:
1. Connect the applicable calibration equipment. Refer to Table
12 - 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
- 400 Ω
• Nominal zero ohms - make a 4-wire connection to the 0 Ω.
