VNA Master Functional Specifications

Definitions

All specifications and characteristics apply under the following conditions, unless otherwise stated:

After 30 minutes of warm-up time, where the instrument is in VNA Mode and left in the ON state.

Temperature range is 23 ºC ± 5 ºC.

All specifications apply when using internal reference.

All specifications subject to change without notice. Please visit www.us.anritsu.com for most current data sheet.

Typical performance is the measured performance of an average unit.

Recommended calibration cycle is 12 months.

Frequency

VNA Master Frequency Range:

MS2026/36C:

5 kHz to 6 GHz

 

MS2028/38C:

5 kHz to 20 GHz

Frequency Accuracy:

1.5 ppm

 

Frequency Resolution:

1 Hz to 375 MHz, 10 Hz to 6 GHz, and 100 Hz to 20 GHz

Typical Test Port Power

VNA Master supports selection of either High (default) or Low test port power. Changing power after calibration can degrade the calibrated performance. Typical power by bands is shown in the following table.

Typical Sweep Speed

The typical sweep speed for IF Bandwidth of 100 kHz, 1001 data points, and single display is shown in the following table. The three receiver architecture will simultaneously collect S21 and S11 (or S12 and S22 ) in a single sweep.
