Tektronix 2232 - Figure 1-3: Checking Probe Compensation

Start Up
Checking the Probe Compensation
NOTE
Always compensate a probe for the particular channel that you use
it with.
Use the following procedure to check the probe compensation:
C] Step 1: Set the instrument controls as described in Setting up the
Display.
C] Step 2: Connect the probe to the channel you intend to use it for.
(If the probe is properly "coded" the volts-per-division readout for the chan-
nel will change to match the attenuation factor of the probe. The
10X probes
supplied with the oscilloscope already have the proper coding.)
C] Step 3: Clip the probe tip to the PRB ADJ connector.
C] Step 4: Use the VOLTSIDIV control to display about 5 divisions of the
waveform.
Step 5: Use the VERTICAL POSITION and HORIZONTAL POSITION
controls to center the display.
Step 6: Check the waveform against Figure 1-3 to see if the probe is
correctly compensated.

Step 7: Adjust the compensation if necessary.
