1 General Information
Connecting the Probe to The Oscilloscope
4 If you are using an N2821A probe, use the Primary Channel
Output field to configure the input channel as a zoomed- in or
zoomed- out channel.
5 If you are using an N2825A user- defined head, in the dialog
box click Add Head to assign a unique name to the head and
enter the resistance of the external R
SENSE
resistor in the
User Def Head Resistance field. For more information, refer to
“N2825A User- Defined Head” on page 37.
Probe Configuration
(InfiniiVision Oscilloscopes)
For N2820A probes, softkeys for the probe’s primary channel
configure both the primary and secondary channel. Unlike
Infiniium oscilloscopes, InfiniiVision oscilloscopes do not
support the assigning of names to identify N2825A/R
SENSE
combinations.
