Check DC voltage measurement accuracy >20 GHz models.
Equipment Required Prerequisites
One DC calibration generator (Item 6)
One SMA male-to-BNC female adapter (Item
19)
Two Dual-Banana Connectors, (Item 5)
The instrument must meet the prerequisites.
(See Prerequisites on page 116.)
WARNING. The generator is capable of outputting dangerous voltages. Be sure to
set the DC calibration generator to off or 0 volts before connecting,
disconnecting, and/or moving the test hookup during the performance of this
procedure.
1. Install the test hookup and preset the instrument controls:
a. Hook up the test-signal source:
■
Set the output of a DC calibration generator to off or 0 volts.
■
Connect the output of a DC calibration generator. (See Figure 8: DC
voltage accuracy test hookup, >20 GHz models on page 177.)
b. Initialize the instrument: Press DEFAULT SETUP.
c. Modify the default settings:
■
From the button bar, touch Horiz/Acq and select the Acquisition
tab.
■
Set the Horizontal Scale to 1 ms/div.
■
Set the Record Length to 5000.
■
Set the Acquisition Mode to Hi Res.
■
Set the Trigger Source to Line.
