Figure 4-8: Bandwidth Test Setup
3.
Press the AUTOSET button.
4.
Set the volts/div scale to 2
mV.
5.
Set the sec/div scale to 200 Ils.
6.
Set the sine wave generator for a 50 kHz reference frequency and adjust
the amplitude for a six division display.
7.
Press the TRIGGER MENU button and set CPLG to
Noise
Reject.
8.
Use the following substeps
(a
to
c)
and the settings and limits given
in
Table 4-3 to confirm the bandwidth of the input channels.
a.
Set the volts/div scale as indicated.
b.
Set the signal generator for the specified amplitude at the reference
frequency.
c.
While confirming the Display Amplitude remains greater than the
minimum number of divisions, increase the signal generator
fre-
quency to 100 MHz or 200 MHz, depending on the instrument
model.
