How to Use the Scanner Interface Board

Activating Scanner Interface

Make the scanner interface valid to perform multi-channel correction and to
input/output signals through the interface connector on the E4980A/AL's rear
panel.
Even when multi-channel correction is used without the interface
connector (for example, controlling a scanner and the E4980A/AL via
GPIB), the following procedure must be performed.
Step 1. Press the [System] key to display the SYSTEM INFO page.
Step 2. Use the cursor arrow keys to move the cursor to the SCANNER I/F field. The
following softkeys are displayed in the softkey label area.
— ON
— OFF
Step 3. Press the ON softkey. The scanner interface is now valid for output/input
signals.

Correction Mode

Set the correction mode to MULTI to use the multi-channel correction function.
Before setting the correction mode to MULTI, you need to set the scanner
interface to ON.
Step 1. Press the [Meas Setup] - CORRECTION to display the CORRECTION page.
Step 2. Use the cursor arrow keys on the front panel to move the cursor to the MODE
field. The following softkeys are displayed in the softkey label area.
— SINGLE
— MULTI
Step 3. Press the MULTI softkey to use the multi-channel correction function.

Test Frequency and Reference Value Entry

It is possible to store the correction data for 201 test frequencies. These test
frequencies are defined and monitored on the CORRECTION page.
On this page, the reference values (REF A and REF B) of the standards used for
LOAD correction are defined at 201 test frequencies. The reference values can
be stored with an appropriate function (FUNC). For example, to use the
