One thing need to be made clear however, the external timebase will not affect the frequency stability in normal operating mode since it is only used for the frequency counter, if you push the

The prints I received were VHS, not on film. I don't know if anyone at Tek even cares after the sellout. Also NTSC is largely going away in a year. -John pdxoregonpete wrote:

as he says a low pass filter will produce a quasi sine wave "gaussian responce"

sorry i wasnt to clear on that, the DDS i was refering to actually has a clock multiplier build in that allow a max of 30MHz i think. Mike Feher <n4fs@...> wrote: If you use 10 MHz as

Sorry, guys, I did not mean for that to go to the reflector. regard,s Tom

They should at least be preserved, the Tek ones I remember went back to the 50's and 60's and where 16MM.

If you use 10 MHz as a clock for a DDS, then, you are just as well off using a flip-flop. Your output will be just a 5 MHz square wave either way. Now if you were to multiply the 10 MHz up first, like

Easy. Take the 5 MHz, split it and mix it with itself. You may want a buffer amp to follow the mixer output. Mini-Circuits Labs has the parts you need. Best, John Richard W. Solomon wrote:

Dick, I've got a new Spectracom 8140T frequency distribution "Tap" module that takes 10 MHz in, buffers it, divides it by 2, then filters the output back to a sine wave. 12 VDC "phantom power"

5MHz was quite common back then, it had to do with the fact that 5MHz XO had a better phasenoise, you will also find 5MHz on many older rubidium and cesium beam standarts. You have basically two

I acquired a box full of plug-ins for my 5245L counter and have a couple of questions. 1. 5253B 50-500 MHz heterodyne oscillator The left most digit is not displayed. i.e., 62.567 is displayed as

Sorry, the sweep calibration is much too inaccurate to use 8601A+8553B as a tracking generator. To use 8601A as a TG, it must be Option 007, and your RF module must be an 8553L, not an 8553B. You

Yes that would help..I just need to know what the little board inside is doing. Most of the enclosure is empty, so I have lots of space to put a single board compute with some extra hardware. Yes I am

Hi HP people! A little post for us. I have a spectrum analyzer HP141T with IF plug HP8552B and HP8553B. The spectrum analyzer cover 0-110Mhz or 0-11Mhz. I have a sweep generator HP8601A that sweep
