Figure 2-4: Probe Compensation Signal Displayed after AUTOSET
Passive probes require compensation to ensure maximum distortion-free
input to the
TAS
475 and
TAS
485 Oscilloscopes. Before taking any mea-
surements using a probe, first check the compensation of the probe and
adjust it to match the channel inputs. The signal source for this check
is
the
front-panel
PROBE COMP signal (Figure 2-5).
1.
Attach the probe to one of the channel input connectors along the lower
right of the front panel.
2.
Attach the probe tip to the PROBE COMP connector.
