TEXTRONIK Oscilloscope 2430A When I bought it I thought I would have probems with it. So far it think it is ok. I am still learning since I bought it to help align by old ham receivers. I didn;'t want to pay a fortune and this was real reasonable. It is large in size and weight because of the era in which it was designed and built. Shipping was rather hefty but received it quickly. Will enjoy using it.

Tek 2430A is 1987 introduced successor to 1986 Tek 2430. It added autoscaling, auto-measures, and longer lasting waveform memories, which 2430 lacked. 2430A is a full-time digitizing scope, so unlike 1982 introduced 468, it is not a combi scope (a term coined by Fluke-Philips indicating a scope that can play as either analog or digital). In 1988 Tek introduced the 2440 which is very similar to 2430A but with 5X the sampling rate. 2430A shares a lot of its DNA with other 2400s, including CRT which is capable of displaying 400+ MHz, but is only used at low frequency in this scope, just fast enough for your eyes not to see flicker. Eventually the cost of such a CRT (whose bandwidth wasn't utilized) spelled the economic end of such scopes, replaced first by cheaper raster CRTs, and later by LCD displays that are cheaper to make (and don't waste bandwidth capability). Present inside a 2430A is a Li battery that back up waveform memories when power is off, and stores calibration fudge factors lookup table. Since these batteries are getting old, count on replacing it. If a startup "fail 4000 FPP" message greets you at turnon, it's probably past due for that. These are complicated instruments, and considering their age, they are entitled to have accumulated several problems, not all of which raise diagnostic fail flags. On the bright side, they were made in vast numbers, so spares are available, their schematics aren't secret (like for newer digitizing scopes), and parts aren't tiny SMT fleas. Their frequency range seems slow by today's standards, but they are plenty fast for many sub-RF applications, especially if you already own an analog 2400. While 2430A communicates over GPIB, this interface is not quite as ready and friendly as the plug & play USB or bluetooth that modern folks have been acustomed to & spoiled by. Considering they cost $8000 new, and we can find them for 1 to 10% of that now, they may still have a place.Read full review
Tektronix 2430A is a very powerful oscilloscope with automatic measurement. Auto measure provides two operating modes: simultaneously measures up to 4 parameters or display a snapshot of 20 waveform parameters. By modern standards, 2430A is slightly difficult to use, but it has good functionality. I recommended to read user's manual before using it.

Tektronix builds high quality equipment and this scope easily fits that category. The 2430A has all the manual and automated capabilities needed for advanced trouble shooting, developing, and experimenting in digital and analog systems, The original factory handbook is availalbe online, in .pdf format, and has detailed tutorial material to help you learn how to use this complex and highly capable oscilloscope.
Verified purchase: Yes | Condition: Pre-owned
Works as it should, wear and tear missing part of one knob, but attenuation is good, just need to replace the plastic portion.
