Run Signal Path Compensation (SPC)
Run SPC when you first receive an instrument, and at regular intervals, for best measurement accuracy. You should run SPC whenever
the ambient (room) temperature has changed by more than 5 °C (9 °F), or once a week if you use vertical scale settings of 5 mV per
division or less.
About this task
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. Failure to run SPC on a regular basis may result in the instrument not meeting warranted performance levels at
low volts per division settings.
Before you begin
Disconnect all probes and cables from the front-panel channel inputs and rear-panel signal connectors.
Procedure
1. Power on and warm up the instrument for at least 20 minutes.
2. Tap Utility > Calibration.
3. Tap Run SPC. The SPC Status readout shows Running while SPC is running. SPC can take three minutes approximately per channel
to run, so wait until the SPC Status message changes to Pass before reconnecting probes and using the instrument.
CAUTION: Y
ou can abort the SPC calibration by tapping Abort SPC. This may leave some channels uncompensated,
resulting in possible inaccurate measurements. If you do abort the SPC, make sure to run the SPC procedure completely
before using the instrument to take measurements.
4. Close the Calibration configuration dialog when SPC has completed.
If the SPC fails, write down any error message text. Make sure that all probes and cables are disconnected and run the SPC again. If
the SPC still fails, contact Tektronix Customer Support.
Compensate the probe
Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. Use this
procedure to adjust probe compensation for probes with a manual adjustment.
The following procedure checks the probe compensation.
1. Connect a supported probe to Channel 1.
2. Connect the probe tip and ground lead of the probe to the PROBE COMP terminals. Connect only one probe at a time to the PROBE
COMP terminals.
