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.
