Follow the steps below to set up the measurement by using the E5052B’s spectrum monitor measurement window.
Press Meas/View > Spectrum Monitor.
You can maximize the Spectrum Monitor measurement window by pressing the Window Max key while the window is selected. You can return to the original size when you press the Window Max key once again.
Start/Center (Stop/Span) > Carrier To - Frequency Band.
Select a frequency band that contains the carrier signal to be measured from the softkey menu list. The ranges of the frequency bands are shown below:
Selectable frequency bands differ depending on whether the E5053A Microwave Downconverter is used and whether the RF input is direct input or downconverter input. For setting of downconverter and external mixer, refer to Setting E5053A Microwave Downconverter

When the downconverter is turned on, the RF input is set to Downconverter, and the external mixer is set to on, setting the carrier frequency band is not available.
Press Start/Center (Stop/Span) > Center.
Enter the sweep center value in the data entry field that appears in the upper part of the screen.
Press Start/Center (Stop/Span) > Span.
Enter the sweep span value in the data entry field that appears in the upper part of the screen.
Otherwise, press Start/Center (Stop/Span) > Start to enter the sweep start value in the data entry field that appears in the upper part of the screen and then press Span (-> Stop) to enter the sweep stop value in the same way.
The same softkey will be displayed by pressing either Start/Center or Stop/Span. You can make the same settings by using either of the two keys.
Allowable setting range for the frequency sweep varies depending on whether the E5053A is turned on/off and the RF input is set to 'E5052B Direct'/'Downconverter.' Possible setting range for the center frequency is possible widest setting range of the carrier frequency bands. More specifically, when possible setting range for the carrier frequency bands are 10M to 1.5GHz and 300M to 3GHz, resultant possible setting range for the center frequency is 10M to 3GHz.

Follow the steps below to enter the maximum level value of the measurement signals that are input from the RF port. For more information, refer to the Specifications.
Press Setup > Reference Level.
Enter the maximum input level in the data entry field that appears in the upper part of the screen.
Press Avg/BW > RBW.
Enter the RBW value in the data entry field that appears in the upper part of the screen.
You can select the value from the options: 1.53 Hz, 6.1 Hz, 24.4 Hz, 97.7 Hz, 391 Hz, 1.56 kHz, 6.25 kHz, 25 kHz, 100 kHz, 400 kHz, 1.6 MHz.
You can specify DC power/control that is applied to the DUT. Refer to Setting DC power/DC control and protection for the setting procedure.
If this function is turned on, the E5052B will adjust the control voltage automatically so that the output signal frequency from the DUT may keep the specified value. For the setting procedure, refer to the Auto Frequency Control Function
