This test checks the accuracy
of the cursors while measuring voltage.
Test equipment:
Tektronix PG 506 Square Wave Calibratfon Generator
Test setup:
Setting s/procedure
:
A Apply
a 1 kHz square wave voltage of IV peak-to-peak to channel A. Use the *STD
AMPL'
output of the PG 506.
B Switch
on the Scope Meter and press the SCOPE
key to get irio SCOPE mode. Now press
AUTO SET
key.
C Set channel
A to 200 mV/div and to AC coupling.
D Press the HOLD/RUN
key tc freeze the display
E Press
the CURSOR DATA key to get into the cursor
menu.
F Press
the CURSOR softkey to activate
the cursor lines.
G Position the first cursor in the horizontal

key to position cursor 1
.
H Position
the second cursor in the horizontal mid
of
tiie
bottom of the waveform. Use the
<CURSOR
-2->
key to position cursor 2.
I
Use the most right
softkey to select NORMAL readout.
Requirements:
The measured voltage
between the cursors is displayed
at the
right
side next to the traces. This
value
must
be 0.98V-.. 1.02V.
