Calibration Procedures (CH1): Frequency
(measure/source)
Note:
Perform just one frequency calibration - use either
the measure function or the source function.
A) Frequency calibration (measure function)
Perform the calibration as follows:
1.
Connect the applicable calibration equipment
specified in Table 10-1; for example see
Section 2.10
.
2.
Let the equipment get to a stable temperature
(minimum: 5 minutes since the last power on).
3.
Set-up the equipment as follows:
Signal generator: Output = 10 V, Unipolar,
Square wave
Frequency = 990 Hz
DPI620G-IS:
Input units = Hz
Input trigger level = 5 V
4.
Use the calibration menu (Ref
: Section 10.2
) to do a one-
point calibration.
5.
Check the calibration is correct: see C) below.
