Overview

N290A/N5291A Systems

The N5290A (900 Hz to 110 GHz) and N5291A (900 Hz to 120 GHz with over range to 125 GHz) are broadband network analyzer systems that utilize compact, broadband remote heads.

These system are comprised of the following components:

N5222B, N5227B, N5242B, or N5247B VNA (see N5290A/N5291A configurations)
N5292A Test Set
N5293A (900 Hz to 110 GHz) or N5295A (900 Hz to 120 GHz) Frequency Extenders

2-Port System

4-Port System

170 GHz and 220 GHz 2-Port Systems

The N5291A can be extended above 120 GHz with the broadband 170 GHz and 220 GHz 2-port systems.

These systems are comprised of the following components:

N5291A170 (Option S93300B):

N5291A with N5295A (see above for components)
170 GHz Frequency Extender
Keysight 11500I test cable for Installation Cal (1.0 mm f-f cable, 8.8 cm)

N5291A220 (Option S93301B):

N5291A with N5295A (see above for components)
220 GHz Frequency Extender
Keysight 11500I test cable for Installation Cal (1.0 mm f-f cable, 8.8 cm) (p/n 11500-60001)

The N5252A is a banded network analyzer solution that uses compact remote frequency extenders with the PXI based VNA, extending the frequency coverage from 60 GHz to 90 GHz.

In its standard configuration the N5252A consists of the following key components:

M9374A or M9375A with option 551 (1 Module per system VNA port)
N5252AW12 Frequency Extenders

N5293A/95A Frequency Extender LED States

Features

Power output of 0 dBm at 110 GHz
Up to 4 millimeter wave ports can be configured
Wide receiver and system dynamic range
Excellent system stability
Compact remote heads with 1 mm connectors
Single module cable for easy setup
Supports several of the existing VNA/PNA-X software applications at millimeter wave frequencies
Available in 2-port and 4-port (standard systems only) configurations
All ports configured for use at millimeter wave frequencies
Measurements down to 900 Hz
Supports both single sweep Broadband and Banded waveguide measurements

Capabilities

ONLY the applications listed in the Supported Applications table are supported
Banded measurements require the N5292A test set
No automatic power leveling. However, after performing an Installation Calibration, the source power at the output of the N5293A or N5295A Frequency Extender is adjustable.
No DC power connector in N5292A test set to provide bias voltage to external frequency extenders for banded measurements
Frequency extender modules cannot be HOT swapped while test set is powered on
Applications that require the use of source and receiver attenuators DO NOT apply to a millimeter wave system
Power level adjustment at the output of the Frequency Extenders is only available after completing an Installation Calibration.
The actual power level can be corrected during a Smart Cal with the Calibrate source and receiver power option selected.
Power calibration requires an appropriate power sensor and meter.
Frequency extender modules cannot be HOT swapped.
All ports must be configured for use with frequency extenders.
Trace noise for Receiver and Wave measurements will degrade for IF bandwidths < 100 Hz.
