Check External Z-AXIS Operation
Connect the leveled sine-wave generator output via
a 50-52 cable and a T-connector to the CH
1
input
connector. Then connect a 50-52 cable and a 50-52
termination from the T-connector to the
EXT Z
AXIS
INPUT connector on the rear panel.
Set the generator to produce a 5-V, 50-kHz signal.
CHECK- For noticeable intensity modulation. The
positive part of the sine wave should be of lower
intensity than the negative part.
Disconnect the test equipment from the instrument.
Check Calibrator Amplitude and Frequency
Set:
CH 1 VOLTSIDIV
A SECIDIV
Connect the 10X Probe to the CH 1
OR
X input
connector and connect the probe tip to the CAL
connector.
Center the vertical display and, if necessary, adjust
the probe compensation for a flat top square-wave
display.
CHECK- For a 5-division display.
CHECK- For a 5-division period (5-divisions
between risetime portions of the display).
Disconnect the 1 O X probe from the instrument.
