Unless it was recently calibrated it wouldn't have been of much use to you anyway. Like most older instruments it was supposed to be calibrated on a 12 month interval. I think the standard procedure

I've mentioned it before, but I found a way to repair the plastic collet that's still holding for about two or three years now. Someone (I think it was Chuck Harris) either made some brass

Jared Cabot (NFM on YouTube) repaired a broken fan collet in a 2445 in this video (https://youtu.be/Rks_AyfJNq4?t=876) and it doesn't look terribly difficult to do, assuming that the collet has not

I've seen that happen too. When there is a Screw AND a Nut... Well, let's just say and unexperienced person can cause a lot of damage. Ross

As a member of the unwashed, I ask: What is a waveform library? Thanking anyone that answers, larry

Luca, I offer Complete Overhaul Parts Kits for the entire 24x5 series, with a solid discount for Tekscopes members. If you want to save yourself a whole bunch of work researching and sourcing all the

I replaced the original blower with a small fan, because the fan collet had broken by someone over-tightening the nut. Those collets must be made of un-obtainium. It's a shame because the original fan

I have recently uploaded the 4 disks originally supplied with the AWG610 to Tekwiki, simply unzip the files and drop them straight to the root directory of 1.44Mb floppy disks.

If I ever get my hands on it I will be sure to upload it here. I've since acquired an AWG610 so I'm also looking for any disks/software not available from Teks website for that. -MH

To reiterate my distress: the manual says that the instrument should have come with "calibration data providing measured frequency correction factors at 10 points" for frequencies between 30 MHz and

Hello John I need 4 2N4122's and 2 2N4275's. I first changed Q834 as that is where the signal ended as the !n4148 D861 made no difference. I then tried swapping Q814 and Q824 and the 7 volts followed

Any luck finding the 063-2171-XX? I need it.

My brain went in circles several times before I thought I understood the circuit. With 1.2V P-P, both the + and the - outputs will both be zero. If the input increases to 1.4V P-P, the + output would

Which transistors do you need, and how many? John

Yes, that's seems to be the issue. There are several routes into the X amp ahead of the x10 switch, not least the Ext X via the trigger circuits, or the X shift controls. Or just dirty earth / screen

C1025 initially charges from rectified line voltage through R1020. Once C1025 has enough voltage across it U1030 powers up. However, current coming through R1020 is not enough to supply U1030, running

Jim, DISCLAIMER: I don't really know what I'm doing, so take any of my answers with a grain of salt. My first choice of capacitor value (the pF range cap) was arbitrary and random, based mostly on

Yeah, I once received 10 each, 2465s of different flavors from a Company Surplus auction. All of those Siemens fan motors - 7 of the 10 - the other ones were Boxer Fans - had the same problem. You are

Never seen that happen and I'd be surprised if that'd ever be the case. In all cases that I encountered, wear of the shaft inside the sintered bronze bushing caused the wobble. Most of the time, the
