Atec Anritsu-S412E - Manual (Page 3)

Definitions
• All specifications and characteristics apply under the following conditions, unless otherwise stated:
• After 15 minutes of warm-up time, where the instrument is left in the ON state.
• Temperature range is 23 °C ± 5 °C.
• All specifications apply when using internal reference.
• All specifications subject to change without notice. Please visit www.anritsu.com for most current datasheet.
• Typical performance is the measured performance of an average unit.
• Recommended calibration cycle is 12 months.
Frequency
Frequency Range: 500 kHz to 1.6 GHz (500 kHz to 6.0 GHz with Option 16)
Frequency Accuracy: 2.5 ppm
Frequency Resolution: 1 Hz
Frequency Range High Port Power Low Port Power
500 kHz to ≤ 3 GHz +3 dB –25 dBm
3 GHz to ≤ 6 GHz 0 dB –25 dBm
Frequency Range Dynamic Range
2 MHz to ≤ 4 GHz 100 dB
4 GHz to ≤ 6 GHz 90 dB
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.
Block Diagram
As shown in the following block diagram, the LMR Master
has a 2-port, 1-path architecture that automatically
measures 2 S-parameters with error-correction precision
inherent to VNA operation.

The above illustration is a simplified block diagram of LMR Master’s
2-port, 1-path architecture. The magnitude and phase information
gained from vector network data enables the LMR Master to
make significant error corrections and provide improved field
measurements.
Typical Test Port Power
LMR 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 Hz,
1001 data points, and single display is shown in the
following table. The two receiver architecture will
simultaneously collect S
