To Identify the
R
SENSE
Resistance Using an ID Resistor
By changing the N2825A’s internal ID resistor, the probe head can
automatically indicate to the oscilloscope the value of the
DUT-mounted
R
SENSE
being used. Up to five dedicated N2825A
probe heads can be configured in this manner using the ID resistor
values shown in
Table 5
Valid N2825A ID Resistors
For example, you might install a 19.6 k
Ω
ID resistor in one N2825A
to identify measurements using a 50 m
Ω
R
SENSE
and a 26.2 k
Ω
ID
resistor in another N2825A to identify measurements using a
300 m
Ω
R
SENSE
.
The first time that you use the modified N2825A,
you must perform a one-time entry of the associated
R
SENSE
resistance on the oscilloscope. For subsequent uses, the
oscilloscope automatically uses the specified
R
SENSE
value for each
N2825A head. You can order additional N2825A heads from
Keysight.

CAUTION
In the following procedure, always wear an ESD wrist strap and work at a
static-safe workstation. Not doing so can result in the probe head
becoming permanently damaged.
