SNA6122A Overview

The Siglent SNA6122A Vector Network Analyzer (VNA) is a versatile tool featuring a frequency range of 100kHz to 13.5GHz, supporting 2-port scattering and differential measurements. Ideal for determining the Q-factor, bandwidth, and insertion loss of a filter, it also offers impedance conversion, movement of measurement plane, limit testing, ripple test, fixture simulation, and adapter removal/insertion adjustments. Additional options available separately include Time Domain (TDR), Spectrum Analysis (SA), Scalar Mixer Measurements, Pulse Measurement, Material Measurement, External Switch Matrices, and a High-performance reference source.

Jumper Interface

The presence or absence of jumpers is determined by some specific measurement function options included with the network analyzer. The SNA6122A includes a front panel jumper and provides the following:

• Altered signal routing through the coupler
• New arrangement of direct source and reciever access
• Goal:
  • Avoid coupling loss in the receive path
  • Increase receiver sensitivity and dynamic range
• Advantage to direct connection to Measure in: Bidirectional calibration & measurement
• Sensitivity increased by value of coupling loss
• Reduced reverse output power
• It can be configured as a dual source structure
• Flexible test configuration:
  • The internal circuit includes switch and combiner, etc.
  • Extend test port through switch matrix SSM/mechanical switch SSU
  • Test power range can be extended by external amplifier or attenuator
• Technical performance source:
  • High power output (+10 dBm)
  • High spectrual purity (harmonic suppression > -30 dBc)
  • High power scanning range (> 60 dB)
• Pulse modulation capability - Built-in modulation/generator
• Technical performance of receiver:
  • large dynamic range, built-in receiver attenuator, 0.5 dB compression point of 10 dBm
  • Wide receiving bandwidth, IFBW max. 10 MHz
  • Flexible frequency configuration of receiver and source

SNA6000A VNA Series

The Siglent SNA6000A series Vector Network Analyzers cover frequency ranges from 100 kHz to 13.5 GHz and 100 kHz to 26.5 GHz. They support measurements for 2/4-port scattering parameters, differential parameters, and time-domain parameters. These VNAs offer five sweep types: Linear-Frequency, Log-Frequency, Power-Sweep, CW-Time, and Segment-Sweep modes. Additionally, they provide scattering-parameter correction using SOLT, SOLR, TRL, Response, and Enhanced Response methods, enhancing their flexibility for R&D and manufacturing applications.
