Moku:Lab’s Frequency Response Analyzer

Compare all frequency response analyzers

Overview

Moku:Lab’s Frequency Response Analyzer enables you to measure the frequency response of a system in both magnitude and phase using a swept sine output from 10 mHz to 120 MHz. Select from between 32 and 512 points per sweep and configure settling and averaging times to balance total sweep duration and signal-to-noise ratio.

Auto-calibration

Isolate the magnitude and phase response of the system under test by calibrating out intrinsic delays and magnitude errors introduced by cables and Moku:Lab itself.

Two-port impedance response

Precise two-port system responses, math channel enables easy graphing of a system’s output – over – input.

Available on Moku:Lab hardware

The digital signal processing power of an FPGA coupled with the high-quality analog front-end ensures that with Moku:Lab you never have to sacrifice performance for flexibility.

Moku:Lab features a suite of twelve different instruments

Replace multiple pieces of equipment with a single device at a fraction of the cost.
