Low-Frequency Probe Compensation
Probe low-frequency (LF) compensation may need adjustment after
moving the probe from one oscilloscope to another. Check the
low-frequency compensation before making critical rise time or
amplitude measurements.
1. Connect the P6562A to the oscilloscope.
2. Remove all accessories from the P6562A probe and attach the
push-in probe tip. Make sure the boot covers the probe’s metal
sleeve.
3. Connect the probe tip to a calibration signal. Most oscilloscopes
have a front-panel test point for this purpose; if yours does not,
use a signal generator that produces a well-formed square wave at
approximately 1 kHz.
4. Adjust the oscilloscope so that it displays two to five cycles.
5. Using the adjustment tool, adjust LF in the probe until you see a
flat-top square wave on the display. See figure 2.
