Analog trigger voltage verification
You must perform analog trigger voltage verification through a remote interface (USB, LAN, or GPIB)
using the TSP command language.
For verification connections, use the same connections that you used to verify the digitize voltage.
Refer to
(on page 2-16) for drawings. See the example code for remote
measure and digitize setup, trigger model, and front-panel user swipe displayed accuracy (Example
code for verifying analog trigger voltage performance).
Use the following values to verify the performance of the Model DMM7510. Actual values depend on
the published specifications (see
Example reading limit calculation
(on page 2-8)).
Analog trigger verifications are not included in the Customer Calibration Data Report.
Set up to verify the analog trigger measure DC voltage
To check DC voltage accuracy of the analog trigger feature, you will:
•
Apply accurate voltages from the calibrator to the Model DMM7510 front-panel terminals
•
Verify that the displayed readings fall within specified limits
Use the values in the following tables to verify the performance of the Model DMM7510. Actual values
depend on the published specifications (see
Example reading limit calculation
(on page 2-8)).
The maximum input voltage between INPUT HI and INPUT LO is 1000 V
peak
. Exceeding this
value may create a shock hazard.
The maximum common-mode voltage (the voltage between INPUT LO and chassis ground) is
500 V
peak
. Exceeding this value may cause a breakdown in insulation that can create a shock
hazard.
