Start Up
Before you use the digitizing oscilloscope, ensure that it is properly installed
and powered on.
To ensure maximum accuracy for your most critical measurements, you
should know about signal path compensation and the proper use of the
P6139A probe shipped with your oscilloscope as a standard accessory.
Signal Path Compensation
Be sure you compensate your oscilloscope for the surrounding temperature.
This action, called Signal Path Compensation (SPC), ensures maximum
possible accuracy for your most critical measurements. See Signal Path
Compensation on page 3Ć128 for a description of and operating information
on this feature.
P6205 Active Probe
Be sure you use the appropriate probe. Do not use the optional P6205
Active Probe to measure signals above ±10 volts since errors in signal
measurement will result. Instead, use the standard accessory P6139A
Passive Probe or one of the passive probes listed in Appendix A under
Accessory Probes. The P6139A probe is for measurements up to
±500 volts.
CAUTION
Using the P6205 Active Probe to measure signals greater than
±40 volts may damage the probe.
To properly install and power on the digitizing oscilloscope, do the following:
