Provisional entry — research in progress

This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.

The Agilent 1742 A Oscilloscope is an oscilloscope used in lab and support equipment for measurement and troubleshooting. The Agilent 1742 A Oscilloscope operates from 100V/120V supplies with a 1AT fuse and from 220V/240V supplies with a 500 mAT fuse, at 48–440 Hz with a maximum power of 190 VA.[1][2]

What it is

The Agilent 1742 A Oscilloscope is an oscilloscope in the lab and support equipment category.[2][4]

How it works

General reference — not yet source-verified

An oscilloscope displays electrical waveforms as a function of time so a technician can observe signal shape, timing, and trigger behavior.

An oscilloscope commonly accepts an input signal, applies vertical and horizontal deflection or digital sampling, and presents the result as a trace for analysis.

Where it fits in the process flow

General reference — not yet source-verified

An oscilloscope belongs in measurement and troubleshooting work rather than in wafer processing itself.

An oscilloscope is used to check signals in instruments, subsystems, and control circuits during setup, maintenance, and fault isolation.

Applications

The Agilent 1742 A Oscilloscope operates from 100V and 120V supplies with a 1AT fuse, and it operates from 220V and 240V supplies with a 500 mAT fuse.[1][2]

The Agilent 1742 A Oscilloscope has a maximum power rating of 190 VA and an operating range of 48 to 440 Hz.[1][2]
