Basic Operation

Selecting the Probe Tip

Use the Probe Tip Selection screen shown below to identify and select the solder tip that you are using with the P76TA adapter. To
display the Probe Tip Selection screen, click the Select button in the Probe Setup screen. (See page 25,

Probe Setup Screen

.) The

P76TA adapter accepts the P7500 Series TriMode solder tips shown in the screen below.

Click on the radio button next to the solder tip
that you are using, and then click OK.
After you click OK, the oscilloscope applies
appropriate DSP (Digital Signal Processing)
signal correction to the measurements that you
take with that probe/probe tip combination on
that channel.
You must match the tip selection on-screen
to the tip that you are using because the
oscilloscope uses a unique DSP

fi

lter for each

solder tip. Inaccurate measurements will result
if the wrong tip is selected.
If you change the solder tip or move the probe
to another channel, you must update the Probe
Tip Selection screen.
