VNA Master Functional Specifications
Definitions
All specifications and characteristics apply under the following conditions, unless otherwise stated:
• After 30 minutes of warm-up time, when 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.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 Frequency Range: MS2026/36C: 5 kHz to 6 GHz

Transmission Dynamic Range
The transmission dynamic range (the difference between
test port power and noise floor) using 10 Hz IF Bandwidth
and High Port Power is shown in the following table.
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.
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 S
21
and S
11
(or S
12
and S
22
) in a single sweep.
