2. Setting External Signal Source

The E5070B/E5071B allows you to control the external signal source that is connected to

USB/GPIB interface.

Preparations for controlling external signal source

To control the external signal source from the E5070B/E5071B, you must connect its USB

port and the external signal source's GPIB connector via the USB/GPIB interface as shown

in Figure 8-3. Then on the E5070B/E5071B you must specify the GPIB address and the

type of external signal source.

Connection between external signal source and E5070B/E5071B

The settings of the USB/GPIB interface must be made in advance. See "Setting the GPIB"

on page 426 for more information.

To use an external signal source, we recommend that you connect the E5070B/E5071B's

internal reference signal output connector and the external signal source's external

reference signal input connector with BNC cable. This ensures stable measurement

because the external signal source is phase-locked on the E5070B/E5071B's frequency

reference signal.
