1 MHz Test Signal
Reduced Amplitude of a
1 MHz Test Signal
Increased Amplitude of a
1 MHz Test Signal
Once compensated, the probe conveys signals to the input channel accurately, without
artificially attenuating or amplifying frequency components of the signal.
Tip
For the most accurate measurements:
•
Compensate probes for each channel of the oscilloscope;
•
Use a compensated probe only with the channel you used to compensate it; and
•
Compensate your probes frequently.

Why Is the ACCESS LED Off When the Chassis Is
On?
The LEDs may not light until the module has been configured in MAX. Before proceeding,
verify that the PXIe-5164 appears in MAX.
If the ACCESS LED fails to light after you power on the chassis, a problem may exist with the
chassis power rails, a hardware module, or the LED.
Notice
Apply external signals only while the PXIe-5164 is powered on. Applying
external signals while the module is powered off may cause damage.
1.
Disconnect any signals from the module front panels.
