c) Rotate VERTICAL SCALE to set the vertical scale of CH1 to 200 mV/div.
3) Enable Fluke 9500B; set its impedance to 50 Ω and select the resistance measurement
function. Read and record the resistance measured.
4) Rotate VERTICAL
SCALE to adjust the vertical scale of CH1 of the oscilloscope to 500
mV/div; then, read and record the resistance measurement value.
5) Turn off CH1. Measure the resistances of CH2, CH3 and CH4 respectively using the method
above and record the measurement results.
3. Impedance test of the [EXT TRIG] channel
1) Disconnect the connections of the four input channels.
2) Connect the external trigger channel [EXT TRIG] of the oscilloscope with the active signal
terminal of Fluke 9500B.
3) Press UTIL Ext impedance to set the input impedance of the external trigger channel
to 1 MΩ.
4) Enable Fluke 9500B; set its impedance to 1 MΩ and select the resistance measurement
function. Read and record the resistance measured.
5) Press UTIL Ext impedance to set the input impedance of the external trigger channel
to 50 Ω.
6) Set the impedance of Fluke 9500B to 50 Ω. Read and record the resistance measured.
