Connect the probe to the oscilloscope.
The probe performs a self test, and then one Input Mode LED remains lit.
The oscilloscope discovers the probe (if this is the first time they are connected), and downloads S-parameter data from the
probe. The oscilloscope then computes the filters. A message displays until the process is complete.
The Probe Setup screen displays (if this is a first-time connection).

Installation
Connect TriMode Adapters to the Probe Body
TriMode adapters are required to complete the connection between the probe and your circuit, and are briefly described below. The
adapters connect the P7630 probe to your circuit through 2.92 mm or SMP cables, or through P7500 Series solder tips, such as the
P75PST Performance Solder Tip. The adapter inputs are polarized, with the A input marked in red and the B input marked in black.
The adapters should be connected to the probe before the probe is connected to the instrument.
1. P76CA-292
Use this adapter with high quality,
skew-matched cables that have male
2.92 mm connectors at the probe end. The
other end of the cables can be customized with
connectors that mate to your circuit.
2. P76CA-292C
This adapter includes a pair of skew-matched,
6 inch cables with male 2.92 mm connectors.
3. P76CA-SMP
This adapter includes a pair of skew-matched,
6 inch cables with female SMP connectors.
4. P76TA
Use this adapter with P7500 Series probe
solder tips. (See page 39,

oscilloscope for automatic identification.
Connect them as follows:
Orient the adapter to the probe body with
1.
the A and B inputs on top, as shown.
Insert the adapter into the probe head.

Functional C heck and Calibration
After you connect the probe to the oscilloscope, perform a functional check using the procedure below.
Functional Check
This procedure checks the four TriMode settings on the probe, using the FAST EDGE connection on the front panel of the
oscilloscope. The A-B (differential mode) is set up and verified first, and then the remaining input modes are checked and
compared to the differential mode measurement.
