Connections for 50 and 62 GHz oscilloscope models, channels 1R- 3R

Procedure

Preset the power meter.

4 Make the connections to oscilloscope channel 1 as shown in the connection diagram

above.

5 Set up the Power Meter to display measurements in units of Watts.

6 Press [Default Setup], then configure the scope as follows:

a Ensure Channel 1 is displayed and all other channels are turned off.

b Set the vertical scale of channel 1 to 10 mV/div.

c Set the horizontal scale to 16 ns/div (to display 8 cycles of a 50 MHz waveform).

Notes

• Connect output 1 of the V241C splitter to the scope Channel n input directly without any additional

cabling or adapters.

• Minimize the use of any adapters.

• Ensure that 1.85 mm connectors are tightened properly:
