Conversion Loss and Frequency Response

9.Adjust the output power of the signal generator for a reading of approximately -10 dBm on the power meter for the 11970K, V or W and for approximately -3 dBm for the 11970A, Q or U. (Make sure that the unleveled light is not on for the 11970V and 11970W. Vary the power by adjusting the rotary vane attenuator.)

10.On the spectrum analyzer, press SHIFT and [MKR/∆ ⇑ STP SIZE].

11.Set spectrum analyzer CENTER FREQUENCY to:

11970K: 22 GHz

11970A: 33 GHz

11970Q: 41 GHz

11970U: 50 GHz

11970V: 62 GHz

11970W: 92 GHz

12.On the spectrum analyzer, press SHIFT and SWEEP, CONT.

13.Set the spectrum analyzer controls as follows:

For 11970K, A, Q or U:

SHIFT, REFERENCE LEVEL, 3, 0, -dB

SCALE ENTER dB/DIV, 2, dB

RES BW, 1, MHz

FREQUENCY SPAN, 2, 0, MHz

CF STEP SIZE, 5, 0, 0, MHz

For 11970V or W:

SHIFT, REFERENCE LEVEL, 3, 0, -dB

SCALE ENTER dB/DIV, 2, dB

RES BW, 3, MHz

FREQUENCY SPAN, 2, 0, 0, MHz

CF STEP SIZE, 1, GHz

Press REFERENCE LEVEL:

11970K: 3, 6, -dBm

11970A: 3, 8, -dBm

11970Q: 4, 0, -dBm

11970U: 4, 0, -dBm

11970V: 4, 8, -dBm

11970W: 5, 6, -dBm
