VectorStar™ MS4640B Series

Measurement Times

Measurement times include sweep time, and band-switching time, in single channel mode. Typical.
20 μs/point is achieved in true swept mode, with 25,000 points, with ALC turned on for level accuracy, with display turned-on for tuning purposes, with

locking turned-on for frequency accuracy and repeatability, with correction turned on to meet published residual specifications, and over the full span of

the product with all band-switch points to fully characterize a device.
