Measuring Input
Resistance for ZIF Probe

Probe Heads
shows the correct setup for measuring the differential input
resistance for ZIF probe heads or the solder-in probe head.
Figure 62
Measuring the differential input resistance of a ZIF or solder-in probe
head
1
Connect the BNC to SMA adapter and BNC to Banana Plug adapters
2
Position the PV fixture on a table top and clamp it with a small bench
vise to steady it. Ensure that the PV fixture is flush with the table top so
that when the banana plugs are probed, it does not rock the PV fixture.
3
Connect the probe amplifier to the oscilloscope or power supply so it
is powered.
4
Connect the ZIF or solder-in probe head to the probe amp and insert it
into the PV fixture as shown
.
5
Depress the pincher fingers on the PV fixture so they open and
carefully insert the tip wires under the pinchers. Release the pichers
once the tips are inserted.
6
, measure the DC input resistance between the
banana plugs. Since one tip wire is connected to the signal line and
the other tip is connected to the PV fixture ground, this is a
measurement of the differential input resistance. It should be 100
kOhms +/- 2% (98 to 102 kOhms).
7
To measure the single-ended input resistance, measure the resistance
between the signal plug of the banana adapter and the probe amplifier
ground, which can be accessed as shown in
(through the
vent window of the probe amplifier).
