e.When the DAC has been adjusted, press Q on the keyboard to exit the program. (If the in- strument has a Down Converter installed, you will be returned to the start of the program to perform this calibration for frequencies of

>2 GHz.)

When the DAC has been completely adjusted, the program will exit to the $ prompt.

e.Record step completion on the Test Record.

3.Perform Log AM calibration as follows:

a.At the $ prompt, type: calterm 113 and press <ENTER>.

b.Set the function generator’s output ￿0.20 volts. Use the COMPL button to toggle the output between –0.20 volts and +0.20 volts.

c.On the computer keyboard, use 1, 2, or 3 to in- crement and 8, 9, and 0 to decrement the value of the DAC’s setting to obtain a 10.00 dB differ- ence in the power meter’s reading when the function generator’s output is toggled.

d.When the DAC has been adjusted, press Q on the keyboard to exit the program. (If the in- strument has a Down Converter installed, you will be returned to the start of the program to perform this calibration for frequencies of

4.Perform AM Meter calibration as follows:

a.At the $ prompt, type: calterm 147 and press <ENTER>.

b.Set up the Function Generator for a 1 kHz sinewave with an output level of 0.354 volts RMS (1 volt peak to peak). When done, press any key on the keyboard to continue calibra- tion.

The $ prompt will appear on the screen when the calibration is complete.

c.Record step completion on the Test Record.
