Oscilloscope roundup?

[Satamax]

Hi everybody!

I was wondering if anybody had a phosphor display scope on the board?

I'd like to do a roundup to know what scopes people have. Please post your scope name and model, and specs, if anything is out of the norm/intresting. Try to avoid coments guys, as it will be better for readability.

I start,

One Tektronix 564B storage oscilloscope.
One THM560 tekmeter batery operated.

[soundmasterg]

Two Tektronix 2235's, capable of battery power or AC operation. Dual trace, 100 Mhz.

[Tom Phillips]

Tek 556 50MHz Dual beam with 1A1 plug ins for 4 Chs total
Tek 465 100MHz Dual Ch
Tek 465B 100MHz Dual Ch
Tek 468 100MHz Dual Channel digital storage

[Steve Conner]

At home:
Tektronix R7603 (100MHz 4 trace rackmount, ex-military off eBay)
Telequipment D34 (20Mhz 2 trace mini battery powered)
Pico ADC212-100 (PC-based 100MS/s DSO)
Game Boy with GBDSO cartridge

At work: (shared between all our engineers)
Tektronix TDS220
Tektronix TDS2012
Pico ADC212-100
Philips 400MHz dual trace analog scope (forgot the model number)

[Mark Black]

Tek 2235, 2335, and 541A

Steve,

The TDS2012 is a color DSO, right? How does its display look to you? Do waveforms display the instant you touch probe to circuit, or is there some latency present?

I'm hoping to try one of the 2004B's first-hand before taking the plunge, but realistically I think that probably won't happen - so any info appreciated.

Hi Ray,

The display looks fine, though it'll never be as good as an analog scope because it doesn't preserve the intensity information that tells you about rise times etc. That is a drawback of all DSOs except for the pricey Digital Phosphor models.

I've never noticed any bothersome latency, the thing is just fine for probing around circuits when troubleshooting. In fact it can sometimes be better than an analog scope. If it gets triggered by a glitch in its auto mode, it'll often leave the transient on screen for you for a second or so. It almost seems to have a tiny brain that figures out the things you would like to see but would miss on an analog scope.

Steve,

Thanks for the info! I should probably just bite the bullet and head into Manhattan some day to see one up close before I buy. I've never actually seen a color display in the flesh.

Tek 541A (faulty PSU, currently)
Scopex 4D-10A 10MHz (old, basic and very useful)

Looking for a Fluke digital storage scope but yet to find one cheap enough.

Anyone tried using their video out?

Just curious if anyone's tried this. My B&K had a video out I never got to try. Many years ago my brother gave me a kit specifically for converting 'scope video to an NTSC TV signal - it's lying around somewhere, unbuilt (I guess any NTSC modulator would work, unless there's something unique about 'scope video).

Oh, yeah - right now I'm limping along with a Fluke 97 ScopeMeter until I find something better. The portability, on-screen measurement readout, good <120Hz display, built-in signal generator, and (relatively crude) auto-set I like; the crawly, black-on-greenish-yellow trace and @500mS latency I could live without.

Scopes:

Hitachi V-650F 60 MHz analog. Dual channel. Dual time base. Delayed triggering. A & B & external triggering. All the bells and whistles. 2 Hitachi 1x10 probes, carrying case, manuals, schematics.

Heathkit O-12 500 KHz vacuum-tube. 1 channel. No frills. Paid $0.99 and fixed it up with a 12AU7, 2 plastic knobs and a little TLC. I had absolutely no need for this scope, but the price was too good to pass it up.

Other Stuff:

HP 3311A Function Generator. 1 MHz.

Tenma 72-475 Sweep Function Generator. 2 MHz.

HP 5300B/5308A Dual channel counter/timer. Stacks on the HP33112A.

OT: I used the 2 function generators, counter, and Hitachi scope to draw the Lissajous figures that I posted in Music Electronics.

Scope talk

My stable of foxy 'scopes, in order of frequency of use:

Tektronix 465B
Leader 1021
Tektronix T922
Hewlett-Packard 1222A
Tektronix 575 curve tracer

The 465B and the Leader are the always-on-the-benches (amp repair bench, pedal assembly bench) ones, the T922 is the backup, and the H-P is for sale.

The 575 is for mad scientist appeal.

The Leader, the T922 and the 575 each have their own Tek carts.

I also have a handy little switch/junction box I built for the amp bench that connects an amp's speaker output to either my speaker or dummy load.

There's a BNC jack for connecting to the scope, and the box puts a 1M resistor in series with the signal going to the scope so that I can see the top and bottom of the waveform from a clipping power amp.

I coined the term Test Equipment And Repair Gear Acquisition Syndrome, or TEARGAS, a form of Gear Acquisition Syndrome.

[sportster4eva]

I have a Nicolet 320 that I use mostly. 100mhz dual channel, storage, A B or ext. trigger.

I have an old Tek 453 Labeled IBM, It uses nuvistors at the front end, and for some other functions!
500khz dual channel. The display still looks good for it's age.

I also have an old Tek 555 scope that I snagged for $0, with extra time base. What a monster that thing is. I have no room for it. I don't know if I have the heart to gut it, but if I did I'd have enough parts to keep me busy long time.
I'm thinking about using it's power supply for a nice bench supply.

[Turbo7MN]

HP 180C from the late 60s/early 70s. Has the 1804A 4-channel input, and 1821A time base, it was actually cobbled together from two non-working scopes. The thing's a monster, but the display's nice and overall I like it.

Wish I could have a few more like you guys .

[J Martin]

I have a Tektronix 05-245(P)U with a TD-1085/U dual time base module and two AM-6565/U amplifiers. A real boat anchor for a solid state scope. It was military surplus refurbished by Tucker electronics, if anyone remembers them. Got it around 1994 or '95. "Built like a tank" as they say.
