Connections

Procedure

Preset the power meter.

2 Ensure that the power sensor is disconnected from any source and zero the meter.

3 Connect the power sensor to the power meter's Power Ref connector and calibrate the

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.

Notes

• Connect output 1 of the 11667C splitter to the scope Channel n input directly using the 11901A adapter

and a connector saver (either 5061-5311 or 1250-3758 depending on the oscilloscope’s bandwidth),

without any additional cabling or adapters.

• Connect the power sensor directly to output 2 of the power splitter using the 11901C adapter without

any additional cabling or adapters.

• Connect the microwave cable directly to output 3 of the power splitter using the 11901C adapter

without any additional cabling or adapters.

• Minimize the use of other adapters.

• Ensure that 2.4 mm and 3.5 mm connectors are tightened properly:

8 in-lbs (90 N-cm) for 3.5 mm

8 in-lbs (90 N-cm) for 2.4 mm
