TRACE ROTATION ADJUSTMENT
NOTE
Normally, the trace will be parallel to the center hor
izontal graticule line, and TRACE ROTATION adjust
ment is not required.
1. Preset the instrument controls and obtain a baseline
trace as described in ‘‘Initial Setup.”
2. Use the Channel 1 POSITION control to move the
baseline trace to the center horizontal graticule line.
3. If the baseline trace is not parallel to the center hor
izontal graticule line, use a small-bladed screwdriver or
alignment tool to adjust the TRACE ROTATION control to
align the trace with the graticule line.
PROBE COMPENSATION
Misadjustment of probe compensation is a source of
measurement error. The attenuator probes are equipped
with a compensation adjustment. To ensure optimum
measurement accuracy, always check probe compensation
before making measurements. Probe compensation is
accomplished by:
1.
Preset the instrument controls and obtain a baseline
trace as described in “ Initial Setup.”
2. Connect the two 10X probes (supplied with the
instrument) to the CH 1 OR X and CH 2 OR Y input con
nectors. Observe that the CH 1 VOLTS/DIV readout
changes from 5 mV to 50 mV when the 10X probe is
attached to the CH 1 OR X input.
3. Remove the hook tip from the end of each probe.
NOTE
While the probe tip is in the PRB ADJ connector,
use care not to to break off the probe tip.
4. Insert the Channel 1 probe tip into the PRB ADJ
connector.
5.
Use the CH 1 POSITION control to vertically center
the display. If necessary, adjust the A TRIGGER LEVEL
control to obtain a stable display on the plus (OUT)
SLOPE.
6.
Check the waveform display for overshoot and
rounding (see Figure 2-14); if necessary, use a small-
bladed screwdriver to adjust the probe compensation for a
square front corner on the waveform.
7.
Remove the Channel 1 probe tip from the PRB ADJ
connector.
8.
Insert the Channel 2 probe tip into the PRB ADJ
connector.
9. Set the VERTICAL MODE to CH 2.
10. Set the A TRIGGER A&B INT switch to CH 2.
11. Use the CH 2 POSITION control to vertically center
the display.
12. Check the waveform display for overshoot and
rounding (see Figure 2-14); if necessary, use a small-
bladed screwdriver to adjust the probe compensation for a
square front corner on the waveform.
NOTE
Refer to the instruction manual supplied with the
probe for more complete information on the probe
and probe compensation.
