Dear TekScopes Could someone a bit more competent than me help with analysing the problem I am having with the Z-Axis Amp on my beloved 475 which has served me incredibly well for over 10 years. The

When I move channels 1 or 2 down the screen the trace is compressed at the bottom. As if the gain near the bottom the screen is about half that at the top. The effect is identical on both channels.

Hello, first post here and first real scope. A tech friend of mine gave me this in broken condition and said I could keep it if I can fix it. So here goes.... It doesn’t boot. Nothing happens when I

hello to all, i can?t find the part 2n5859 here in Mexico, this part number is critical in the -15v regulator performance or permits substitution ? any possible subtitutes? any help will be really

Thanks a lot, H?kan. Will try that during the coming week and share result. Raymond

If you connect a PC running a terminal program to the serial port of the THS you can try sending first PASSWORD PITBULL and then ERRLOG CLEAR. It doesn't clear any RS232 errors but it resets the

Next thing to try is disconnecting the input wire to the x4 voltage multiplier. Then connect the two coax feeds. If the main supply then comes up OK, the fault is with the multiplier. If it is still

U2?

Connecting the PG508 to the scope and the servo in parallel should be fine. I would connect it to the scope first to get the PWM voltage right, since the PG508 is capable of voltages outside of what

I bought a PG 508 to use to configure some model airplane servos whose actions are determined by Pulse Width Modulated signals. I have one question about the CAL pots on some of the controls on the PG

Chuckle.? There's a bunch of us "old crumbly one's" here.? I believe the correct pithy term is curmudgeon.? ;-) Mark

Oh yes, you do. Every electronics hobbyist should have a variable transformer. They are extremely handy for all sorts of things. --Eric Sent from my Samsung Galaxy smartphone.

Noise on the “mains” are often an issue on modern “all electric” ships where I have spent way too much time and with the advent of so many poorly designed switching power supplies and drive

<SNIP> Sounds like something is not regulating. What it sounds like is that you're getting coupling from the AC line into the power supply output. First thing I'd do is to (if you have a variac

The recent topic about the THS720/THS720A encourages me to submit an issue that I've had with my THS720A for some time. The instrument is in pristine condition, both cosmetically and technically.
