Keysight N2790A Differential Voltage Probe User Guide
The following procedures can be used to test and verify the DC differential
gain accuracy and bandwidth of the N2790A high voltage differential
probe.
Table 7
Critical Specifications
Bandwidth: >100 MHz
1 MΩ/50Ω selectable input
Amplitude accuracy: less than or equal to
0.25%
1 MΩ / 50Ω selectable load
Sine wave greater than or equal to 25 MHz
BNC (f) to Dual Banana (m) Adapter
50Ω precision feed through
These procedures require the application of high voltage to the inputs of
the N2790A probe. Because the adapter used in this procedure has
exposed metal surfaces, only qualified personnel should perform any
testing with voltage levels exceeding 30V rms. All pertinent safety rules
and guidelines for elevated voltage measurements should be followed
and adhered to.
Generator produces hazardous voltages. To avoid risk of shock, do not
touch exposed metal parts after the generator output is enabled.
