Impedance Test
Specifications:
Input Impedance
1 MΩ ±2% (0.98 MΩ to 1.02 MΩ)
Test Devices: Fluke 9500B or Digital Multimeter and BNC (male) to Dual-banana Plug Cable. In this
manual, the test device is Fluke 9500B.
Test Procedures:
1. Impedance test of CH1 and CH2
1) Connect the active head of Fluke 9500B to CH1 of the oscilloscope.
2) Configure the oscilloscope:
a) Press CH1 in the vertical control area (VERTICAL) at the front panel to enable CH1.
b) Rotate VERTICAL SCALE to set the vertical scale of CH1 to 100 mV/div.
3) Enable the Fluke 9500B and select the resistance measurement function, read and record
the resistance measurement value.
4) Rotate VERTICAL SCALE to adjust the vertical scale of CH1 to 500 mV/div; then, read
and record the resistance measurement value.
5) Turn CH1 off. Repeat the above test steps to test CH2 and record the test results.
2. Impedance test of [EXT TRIG] channel
1) Disconnect the connections of the two input channels.
2) Connect the active head of Fluke 9500B to the external trigger channel [EXT TRIG].
3) Enable the Fluke 9500B and select the resistance measurement function, read and record
the resistance measurement value.
