11. Repeat the procedure for all remaining channels as follows:
a. Push the front-panel button to deselect the channel that you have already
tested.
b. Push the front-panel channel button for the next channel to be tested.
c. Connect the signal source to the input for that channel.
d. Repeat the procedure from step 5 until all channels have been tested.
12. Press the Menu Off button.
For the MSO5000 series only, this test checks the threshold accuracy of the digital
channels. This procedure applies to digital channels D0 through D15, and to
channel threshold values of 0 V and +4 V.
1. Connect the P6616 digital probe to the MSO5000 series instrument.
WARNING.
The generator is capable of providing dangerous voltages. Be sure to
set the generator to off or 0 volts before connecting, disconnecting, and/or moving
the test hookup during the performance of this procedure.
2. Connect the DC voltage source to the digital channel D0.
If you are using the Fluke 9500 calibrator as the DC voltage source, connect
the calibrator head to the digital channel D0, using the BNC-to-0.1 inch
pin adapter listed in the Required Equipment table. (See Table 4-1 on
page 4-1.) Be sure to connect channel D0 from the probe connector to both
the corresponding signal pin and to a ground pin on the adapter.
3. Push the front-panel Default Setup button.
