High precision differential probe
Gxxx: 1 kV DC High Precision Differential Probe (Option, to be ordered separately)
High precision 10 MΩ differential probe (HDP) to be used in combination with GN610, GN611, GN610B and GN611B acquisition cards. Reduces
the resistive/current load on the device under test by increasing the input impedance to 10 MΩ with 0.2% in
-
accuracy. The use of the 10:1
divider reduces the lowest user range to
±
0.1 V (
±
0.2 V when using GN610/GN611). The highest input range is
±
1000 V due to the maximum
voltage rating of the probe.
The HDP10H probe is optimized to match the 33 pF input capacitance when using the ranges
±
10 V up to
±
1000 V.
The HDP10L probe is optimized to match the 57 pF input capacitance when using the ranges
±
10 mV up to
±
5 V.
