(snip) 1MHz signals My humble twopence: Crappy rule of thumb! Few years ago while integrating an ATE we had a 1MHz square signal we thought it wouldn't need matching pretty much for the same

Be careful using "network-grade" coax terminators for high-frequency RF. The ones I've seen become reactive as heck above 50 - 100 MHz or so. Unless you have a way to check their return loss at the

Jim asks: Basically, the phenomenon you're trying to avoid here is signal reflection. What coax does is provide a path with a known impedance to carry the signal from point to point without changing

A few months ago, Dean Huster had included the following in a post: "You don?t HAVE to use a termination on coax if it?s a low-frequency signal. For high-frequency or fast-pulses, yes, you must

Hi Stephan, Try asking to "Deane Kidd" <dektyr@...> He has lots of Tek spares. I have bought from him several times. Good

Hallo! I`m sorry for my bad english, but i do my best... In the 7B538 (Trigger-Modul) is an ic broken. It is an ECL Dual 275 Mhz Latch, named MC1669L. Do you knew a cross-reference ic? Ore do you

If you connect the ground lead to the auto's ground, you have a capacitive pickup from the ignition wire. This will give you plenty of voltage, but also plenty of noise from nearby wires. If you

Thanks for the replies. Nice to know I was on the right track. One quick follow-up question, though. Would I place the ground of the trigger to one end of the "pick-up" loop on the plug wire, or

Jim This will work, you may want to check the voltage spike with your scope before you apply it to your trigger input. I did this quite a few years ago and I found that 3 turns around the spark plug

I know this is a little off-subject, but it does relate to using an oscilloscope. Without going into to details about why I want to do this, I'll pose the following scenario: Suppose I want to

Hi All, I am still looking for a Vertical Amplifier IC for a Tektronix 2235A Oscilloscope. Tektronix Part Number is 234-0133-20 Can anybody help? If not, does anyone have a 2235A for

Greetings, Rob; some tester so I in the me know Thank you for the generous offer. I may need to take you up on it. It appears I may be down one or two to fill what P-Is are in the pile. Best Rgds;

Greetings, Stan; I appreciate your response. The refs were most useful and informative. Seems this should be easy to identify using the cal source into the P-I under test. The latest E55L price

Problem is the manual I have is for a 5103N D11/D15. I have r242 as 22k, r101 as 100, r251 as 5.6, r239 as 100, r274 as 1m, and r213 as 62k. Need to know if these are listed as the same for a D10

Does anyone have a Tek 455 service manual for sale? Could also trade other manuals, probes, plugins, etc. I've already tried the usual dealers. Thanks...

Hi All, Has anyone a spare Tektronix 2432 Rear Cover lying around? Tek part number 200-2961-00. Thanks. Andrew

Greetings; Middle-aged Tek gear has it's share of this miserable material and it's close relatives in cracked/shattered condition. While at a motorcycle rally last week, I saw demonstrated an
