Moving slightly OT, I think Stanford Research are the Lock-In Amplifier people. (Among others) Talking $$$$ tho' Tim

Yes, and some Tektronix cameras could mount a pre-fogging device, using red LEDs to 'flash' the film before, during, or after exposure. Could double the ASA of Polaroid (r) 3000 Tim P

Just a thought, but are the two screws holding the 'B' sub-chassis tight ? There are two single-pin connectors nearby. best regards Tim

I have just recollected that this can mean the CMOS coin-cell needs replacing. Tim gmail.com@groups.io> wrote:

Bruce, I have a very similar problem; I get a message saying my clock is ahead. (I am on Greenwich (UK) Mean Time) Walter's site does the same. Tim

Couldn't agree more, Jeff - I, too, am humbled by the collective spirit of this group; expertise freely given, often 'above and beyond' Re Harvey's List (deliberate capitals !) may I respectfully sugg

Did Tek make their own knobs or outsource ? What about the earlier 'Black & Red' sets for 500 and 560 series scopes? I think there is an interesting story to be told about knob design and layout (ergo

Is there a MOD sticker on it anywhere ? Maybe not relevant, but there was a MOD to the 7B71 for use with the 7704A DPO. Just wondering whether they both (7B70 / 7B71) needed a MOD for the DPO . Hakan'

Recent talk of the 7S12 prompted me to exhume my one. It lacks the 015-1017 cable from the pulser to the S6 loop-thru. I am using a SMA patch cable of six inches, and the 7S12 works OK, but I would pr

I have a 7S12 that 'half-works', in that I see the pulse from the S52 / S6 combo and I get the step-response from a length of cable BUT, the Time / Distance crank does nothing to the display and the L

My Peak DCA55 often misidentifies some Germanium transistors as BiColor LEDs. In particular those such as 2N2209 with TO7 bases. (e-b-Case-c; the Case lead has been clipped). Is this possibly Tin-Whis

Pre-retirement, I worked for a University in UK. Almost overnight, it seemed, many of the research departments decided to 'go computer', and there was a mass dumping of analog equipment, particularly

And then there is the 7A42 plug-in, the logic-triggered amplifier which can trigger on Boolean AND / OR / NOT etc. on 4 inputs. Tek recommended use with the P6230 Variable Bias probe for probing ECL l

Tekwiki mentions the Oregon Analog ASM7 which does exactly that, although I've never seen one, or heard of anyone having one. Wonder what happened to it? (Pics under 7000 3rd party) Tim
