How to Measure Input Resistance and Capacitance
gjh064.eps
You can press the MODE softkey to cycle through the functions in the order shown, or
you can press
P
to return directly to the OTHER modes menu.
Each option in the Impedance/Capacitance (MEAS Z) menu is described below.
•
Measured @ SCOPE terminal
Indicates the location of the measured input.
•
MEASURE
Indicates the type of test. You can select res 50
Ω
or res 1 M
Ω
termination (for impedance) or cap (capacitance).
•
MODE
Indicates the Calibrator is in MEAS Z mode. Use the softkey to change
modes and open the menus for the other oscilloscope calibration modes.
If you have selected Capacitance measurement, the menu appears as follow:

•
SET OFFSET With the cable disconnected at the oscilloscope but still connected at
the Calibrator, press SET OFFSET to cancel the capacitance of the Calibrator and
cable. Press again ( CLEAR OFFSET ) to cancel the offset.
Input Impedance Measurement
With MEAS Z mode selected, perform the following procedure to measure the input
impedance of an oscilloscope:
1.
Use the MEASURE softkey to select “res 50
Ω
“ or “res 1 M
Ω
“ termination.
2. Connect the SCOPE terminal on the calibrator to Channel 1 on the oscilloscope.
3. Press
O
to initiate the measurement.
Input Capacitance Measurement
With MEAS Z mode selected, perform the following procedure to measure the input
capacitance of an oscilloscope:
