Fluke PM3370B manual

V

-Peak detection for the capture of glitches as narrow as 5 ns.

-Pattern, State and Glitch triggering (2 ns) (2 channel models; 4ns Glitch triggering only)

-Event delay and pretriggering and posttriggering.

-TV triggering including HDTV and TV line selection.

-Serial interface for printing and plotting.

-Averaging to reduce signal noise and to increase the vertical resolution from 8 to 16 bits.

-Advanced mathematics, including digital low-pass filtering. A Math+ option adds integration, differentiation, histogramming, and FFT.

-Sine interpolation and magnification which enables true to life four channel single shot acquisitions with a timebase up to 625 ns/div (32x magnified)

-A delayed timebase with full trigger features.

-An RS-232 (EIA-232-D) interface (standard) and an GPIB/IEEE-488 interface (optional).

-Autocal for automatic fine tuning of all circuitry to achieve maximum accuracy under all user conditions.

-Closed case calibration for efficient maintenance of traceable calibration at minimum cost.

The following options are available:

-A MATH+ option with more automated measurement functions including envelope and measurement pass/fail testing. Also included in this option are Integration, Differentiation, Histogramming, and FFT.

-Memory extension offering 32K acquisition length and the ability to store 156 traces (of 512 samples each) in memory for 2 channel versions.

-IEEE-488.2 interface using the new SCPI (Standard Commands for Programmable Instruments) industry standard for remote control of test and measurement equipment.
