Check DC gain accuracy ≥4 GHz ≤20 GHz models.
Equipment required
Prerequisites
One DC calibration generator (Item 6)
One SMA male-to-female BNC adapter (Item
19)
The instrument must meet the prerequisites.
(See
on page 116.)
WARNING.
The generator is capable of outputting dangerous voltages. To avoid
injury, be sure to set the DC calibration generator to off or 0 volts before
connecting, disconnecting, and/or moving the test hookup during 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. Set the
DC impedance of the generator to 50 Ω.
■
Connect the generator to
Ch 1
through an adapter. Refer to the
following figure.
Figure 14: DC gain accuracy test hookup, ≥4 GHz, ≤20 GHz models
b. Initialize the instrument:
Press
Default Setup
c. Modify the default settings:
■
From the tool bar, touch
Horiz/Acq
and select the
Acquisition
tab.
■
Touch
Average
and set the number of averages to
16
.
2. Confirm input channels are within limits for DC gain accuracy
. Do the
following substeps - test Ch 1 first,
since Ch
1 is already selected from step
a. Select an unchecked channel:
■
From the tool bar, touch
Measure
and then
Clear All
to remove the
previous measurement.
■
Press the Vertical button of the channel just confirmed to remove the
channel from the display.
