Connecting the N1022A
panel. Connecting to an Aux Power connector prevents the probe from being
automatically calibrated.
3 Connect the probe output to the probe adapter input. The probe tip should not
be connected to a device under test at this time.
CAUTION The probe power cable connector automatically locks in the mating power
connector. To separate the connection, you must pull on the knurled part of the
cable connector housing. This releases the lock. If you pull directly on the
power cable, the connectors will not release and may damage the connector or
cable. An effort has been made to design this active probe adapter to take more
than the average amount of physical and electrical stress. However, the
technologies necessary to achieve high performance do not allow the probe to
be unbreakable. Treat the probe adapter with care.
NOTE During operation, the N1022A probe adapter’s temperature may feel warm
when you touch it. This is normal and does not indicate a problem.
NOTE Before using the active probe adapter with an active probe, perform a probe
calibration. When the probe has been calibrated, the dc gain, offset zero, and
offset gain will be calibrated.The degree of accuracy specified at the probe tip
is dependent on the instrument system specifications.
4 If the Infiniium DCA is in operation, the Probe Channel dialog box will appear
on the instrument display screen. See Figure 1 on page 7.
5 In the Probe ID list, click the probe model that is currently connected to the
probe adapter. This will ensure that the correct probe is specified to the
instrument.
NOTE If you are using an AutoProbe style probe that is not listed in the supported
probe list, select one of the probes from the supported list that is closest in type
to your unspecified probe.
When the Infiniium DCA is not in operation
If the probe and probe adapter is connected to the module front panel
when the DCA is not in operation, the Probe Channel dialog box will not
appear on the instrument display screen when the DCA is turned on. To
open the Probe Channel dialog box, choose Setup > Channels > Chan-
nel X, then click Probes.
