Getting acquainted with the oscilloscope
Signal path compensation (SPC)
Signal Path Compensation (SPC) corrects for DC level inaccuracies in the internal signal path caused by temperature
variations and/or long-term signal path drift. You should run the SPC whenever the ambient (room) temperature has changed
by more than 10 °C, or once a week if you use vertical scale settings of 5 mV per division or less. Failure to run a SPC may
result in the oscilloscope not meeting warranted performance levels at those volts per division settings.
To compensate the signal path for all channels:
1.
Power on and warm up the oscilloscope for
at least 20 minutes.
2.
IMPORTANT: Remove all input signals
(probes and cables) from channel inputs
and the
Aux Out
connector on the back of
the oscilloscope.
3.
Push

.
4.
Push the

side-menu button.
5.
Push the
Calibration
side-menu button.
6.
Turn the
Multipurpose
knob to select
Signal Path
, then click the
Multipurpose
knob to start the SPC process.
The oscilloscope shows a Signal Path Compensation information message.
7.
Push the
Compensate Signal Paths
side-menu button to start the process.
The screen shows rotating dots while the SPC is run. The oscilloscope displays a message when the SPC is complete.
SPC can take several minutes to run, so wait until the oscilloscope shows a message that SPC is completed.
8.
Push
Menu Off
to remove the message and menus.
9.
Reconnect probes to the oscilloscope.
