Conguring the
HP 71500A
This chapter describes how to congure an RF source, control the display, and obtain prints and
plots of the display.You can also prevent access to selected information. To control the pulse
generator, refer to Chapter 3, \Performing Pulsed RF Measurements."
Browse this chapter before beginning measurements.Your rst task should be ensuring that
the microwave transition analyzer shares a frequency reference with and has control of an RF
source. The required cable connections are shown in the following gure. Refer to the sections
\Using a Common Frequency Reference" and \Conguring the RF Source" in this chapter.

Conguring the

HP
71500A
Using a Common Frequency Reference
For most measurements, the frequency reference of the microwave transition analyzer and
RF source must be shared. You can either lock the RF source to the HP 70820A's 10 MHz
frequency reference or lock the HP 70820A to the RF source's frequency reference. When an
external reference is used, the annotation
EXT
appears on the display.

When the instrument is turned on (or the

key is pressed), the microwave
transition analyzer determines if an external reference signal is present at the rear-panel 10
MHz REF INPUT connector. If a signal is present, the external reference is automatically
selected.
To lock on the HP 70820A frequency reference
1. Connect the rear-panel 10 MHz REF OUTPUT connector to the RF source's reference input
connector.

sure to use the HP-IB connector on the rear panel of the HP 70820A. Do not connect the bus to

To select the source type
The microwave transition analyzer must know the model number of the RF source. Be aware
that some available sources have more features than others.For example the HP 3325A/B
synthesizer/level generator does not have an internal pulse modulator.
When an RF source is selected, the microwave transition analyzer searches the appropriate
bus for the source at the default address. If the source is not located, an error message is
displayed. Use the
