Calibrating Active Probes
Use this procedure to optimize gain and offset accuracy at the probe tip for each active probe.
Allow the instrument to warm up for 20 minutes before performing this procedure. Then complete
the following steps:
1 If you have not already done so, connect the probe to the instrument.
2 Connect the probe to the probe compensation terminals as shown. Connect only one probe
at a time.
3 Select Probe Cal… from the Vertical menu to open the Probe Calibration control window.
4 Select the channel to which the probe is attached.
5 Click Calibrate Probe to begin the calibration procedure. The Probe Status indicator
changes to Pass when the procedure is complete. If the procedure does not pass, contact
your local Tektronix service personnel.
6 Remove the connections from the terminals.
Calibrating Passive Probes
Use this procedure to optimize gain and offset accuracy at the probe tip. Allow the instrument to
warm up for 20 minutes before performing this procedure.
If you have not already done so, perform the low frequency probe compensation for passive
probes.
Note
The probe calibration procedure is not recommended for the P5050 passive probes. These probes
have little gain or offset errors. However, you should perform this procedure for other passive
probes.
Complete the following steps:
1 If you have not already done so, connect the probe to the instrument.
2 Connect the probe to probe compensation terminals as shown. Connect only one probe at a
time.
3 Select Probe Cal… from the Vertical menu to open the Probe Calibration control window.
4 Select the channel to which the probe is attached.
5 Click Calibrate Probe to begin the calibration procedure. The Probe Status indicator
changes to Pass when the procedure is complete. If the procedure does not pass, contact
your local Tektronix service personnel.
6 Remove the connections from the terminals.
