Basic Operation

Required Equipment

1 Basic Operation

This application sheet describes the use of an R&S ZVA110 vector network analyzer with
two external test sets for 2-port transmission measurements.

One-port reflection measurements can be performed in a similar way using a single
external test set.

1.1 Required Equipment

The R&S ZVA110 system is delivered with all measurement equipment needed. An addi­tional 1 mm calibration kit is required for system error correction (calibration).

1.2 Measurement Principle

The principle of the measurement with external test sets is described at the beginning of
the R&S ZVA110 Quick Start Guide, stock no 1314.4502.62.

The measurement involves the following steps:

1. Activation of the "ZVA110-BU" mode for measurements with external test set

2. Entry of power coefficients (when an external test set is used for the first time).

3. Connection of the external test sets

4. Power and frequency settings

5. Power calibration using an appropriate external power meter

6. System error correction (calibration) using a suitable calibration kit

7. Connection of the DUT and measurement

1.3 Activating the ZVA110-BU Measurement Mode

After a factory preset, the R&S ZVA67 is configured for measurements using the internal
test sets. You have to activate the "ZVA110-BU" mode explicitly before you connect the
external test sets.

To (re-)activate the "ZVA110-BU" mode,

1. Click "System > System Config ..." and open the "Frequency Converter" tab of the
"System Configuration" dialog.

2. Select "Type : ZVA110-BU".

3. Click "Apply" to activate the mode.
