An oscilloscope is an essential item of test equipment. It enables you to look at the waveform of a signal with a display of amplitude vertically against time horizontally. I currently have 2 Oscilloscopes with a bandwidth from 50MHz to 300MHz. Ideally you need an oscilloscope with a bandwidth 5 times higher than the highest frequency you want to measure.
Tektronix 468 Digital Storage Oscilloscope
This has a 100MHz non-storage analogue bandwidth and a 10MHz digital storage bandwidth with a 10cm x 8cm screen. With 2 vertical channels of 5mV to 10V per division and 20ns to 5s per division horizontal sweep rate, plus intensified and delayed timebase.
Also included is a DMM which is operated with cursors for time and voltage on the waveform displayed. Other features are: X-Y mode, Z axis input, trigger display.
This is my main bench Oscilloscope.
I have 4 oscilloscope probes: 2 are ISO-TECH x1 and x10; 1 is a Greenpar x1 and x10; and 1 is unbranded x1. These are all general purpose 100MHz probes.
The HP 1980B Oscilloscope
has been SOLD
so I am looking out for another Oscilloscope as a backup to the Tektronix 468
and maybe with a higher bandwidth.
3 used Oscilloscopes have been acquired as part of a 'Job Lot'. The Oscilloscopes are a LeCroy 9310 300MHz, a HP 54501A 100MHz and a Hitachi V-525 50MHz. All 3 are faulty so will take some time to repair.
The LeCroy Oscilloscope has been repaired. This is a DSO (Digital Storage Oscilloscope) and has some very advanced measurement features including FFT (Fast Fourier Transform) for spectrum analysis. For details seeLeCroy 9310 Dual 300MHz Oscilloscope
. I use this Oscilloscope on a trolley for any accurate or complicated measurements.
The HP 54501A 100MHz Digitizing Oscilloscope intially worked correctly then developed a power supply fault. This has been SOLD as I do not need 2 DSOs.
