Anritsu 37325A Vector Network Analyzer, 40 MHz to 13.5 GHz

Product Documentation

Description

The Anritsu 37325A Vector Network Analyzer, 40 MHz to 13.5 GHz is high performance tools designed to make fast and accurate S-parameter
measurements of active and passive devices across the 40 MHz to 13.5 GHz range. These network analyzers integrate a synthesized source, S-parameter test set and tuned receiver into a single compact package that is ideal for bench-top testing.

High throughput measurements are achieved in each model through the use of fast, 12-term error corrected sweeps, fast GPIB data transfers and an intuitive user interface. All measurement results are displayed on a large LCD color display or on an external VGA monitor.

For maximum productivity, the VNAs include as standard features:

  •  Fast Sweeping Synthesized Source
  •  Auto Reversing Test Set
  •  Solid-State Transfer Switch
  •  Four Independent Displays
  •  Four Channel Receiver
  •  Internal Hard and Floppy Disk Drives
  •  LRL/LRM Calibration
  •  Adapter Removal Calibrations
  •  Fast Measurement Throughput via GPIB

Number of Channels: Four independent measurement channels.
Parameters: S11, S21, S22, S12, or user defined combinations of a1, a2, b1, and b2. All measurements are made without the need to manually reverse the test device.
Measurement Frequency Range: Frequency range of measurement can be narrowed within the calibration range without recalibration. CW mode permits single frequency measurements, also without recalibration. In addition, the system accepts N discrete frequency points where 2 ≤ N ≤ 1601.
Domains: Frequency Domain, CW Draw, and optional High Speed Time (Distance) Domain.
Formats: Log Magnitude, Phase, Log Magnitude and Phase, Smith Chart (Impedance), Smith Chart (Admittance), Linear Polar, Log Polar, Group Delay, Linear Magnitude, Linear Magnitude and Phase, Real, Imaginary, Real and Imaginary, SWR, Power.
Data Points: 1601 maximum. Data points can be switched to a value of 801, 401, 201, 101 or 51 points without recalibration (if 1601 points were used in the calibration). In addition, the system accepts an arbitrary set of N discrete data points where: 2 ≤ N ≤ 1601. CW mode permits selection of a single data point without recalibration.

LCD: Color, 8.5″ diagonal.
Trace Color: The color of display traces, memory, text, markers and limit lines are all user definable.
Trace Overlay: Displays two traces on the active channel’s graticule simultaneously. The overlaid trace is displayed in yellow and the primary trace is displayed in red.
Trace Memory: A separate memory for each channel can be used to store measurement data for later display or subtraction, addition, multiplication or division with current measurement data.

GROUP DELAY CHARACTERISTICS
Group Delay is measured by computing the phase change in degrees across a frequency step by applying the formula:
τg = −1/360 dφ/df
