When one has 2 sources whose frequencies are equal to better than 1Hz an analog linear phase comparator can be used to determine the frequency difference with a phase comparator system noise level of around 2E-11/Tau to 4E-11/Tau, where Tau is the KO4BB. One of the least difficult to receive is a beacon around 2263. GPS signals have good long term stability (> several hours) but short term stability is affected by propagation conditions, atmospheric conditions, receiving antenna effects, multipath and other short term impairements. While it started with manuals I had scanned myself, most manuals available today have been submitted by users and visitors of the site. Home; Manuals; Timing; Ham Radio; Test Equipment; Electronics If the oscillator you are testing is very clean, the clock shaper and dividers must be designed accordingly so that they do not contribute appreciably to the noise of the oscillator under test. Click on "Manuals" then use the search But if you want to track or trend your 3458A by parameter - or to use its calibration test data as correction constants in your processes - then you must have the Standards Lab cal. The clock shaper is the circuit that converts the sinewave from the oscillator to a digital signal suitable to drive the dividers. php(544) : eval()'d code on line 6 Notice: Undefined variable: f in /var Pulse Extender.

The files will also show up in the "Recent Uploads" directory but not in the Upload log. (test equipment, ham radio or timing related) that I do not have, feel free to upload them. It takes a narrow (typically 10uS) 5V TTL level positive going pulse and generates a wider (nominally 1mS when powered from 9-12V), RS-232 level pulse of the same polarity on the output.

Nostalgia Air - lots of schematics for early radios, but some test equipment is there, too. se from [time-nuts] Feb 15, 2019, 5:01 PM Hi all, Since I have seen people asking for something like this before: I made an interface for connecting a more commonly available display to a 53131A, useful if the VFD (display) is worn out. The call sign is not changed in the ADIF file. (The MU My Philosophy About Test Equipment Manuals Since I host a number of free manuals in pdf on my web site, here my take on the subject: 1) we need quality outfits such as Artek Media, Category three are precision adapters, usually adapters with high repeatability and low reflection coefficient, everything you use around a VNA or to calibrate equipment should be in this KO4BB Manual Directory - Test Equipment + other manuals. 2 MB download) which includes a non-functional version of the program's Manuals, Timing, Ham Radio, Test Equipment.

If caugth before the leaking starts, the batterys can be replaced and excanged for 3 regular NI-CD or NI-MH batterys. Here you can find a fairly large Test Equipment and Ham Radio Manuals repository, covering (mostly) obsolete test equipment such as HP/Agilent/Keysight, Tektronix, Fluke and many Ham Radio Hardware Projects: The Tower Project: notes on tower design and pictures taken during construction. Thanks KO4BB. This program is designed to download screen shots or waveform capture data from a scope in the Tektronix TDS series via RS-232 or GPIB interface (using a Prologix adapter).

The 7L18, 492 and 494P are quite respectable instruments, even compared to modern gear, in terms of sensitivity, spurs, stability and relatively fool-proof operation. Software such as MMTTY has the capability to key the rig via the serial port, so I thought about writing a program that would essentially emulate the Sound Recorder utility, but with the capability to key the rig via the serial port when playing back sounds Soldering is considered a bad thing to do and most companies don't even mention the word in their app notes, the problem is that the leads on the diodes are consisting of gold, regular solder has the habit of having a affinity for gold so in other words it will dissolve the gold from your leads, every one who ever tried to repair a hairline crack on a hybrid microwave A while ago I bought a couple of 4352A VCO Analyzers, mainly out of curiosity and because they were cheap. It looks like all vendors have switched to other, newer members of the family, the closest being the JDY-33.

The download comes in 2 pieces, the base install which includes a non-functional or often older version of the program's exe and all the dlls and controls, and the latest version of the executable. Also, while the cost of building two transverters is obviously greater than the cost of building one, if you shop wisely and as I did, do not try to make two top-shelf units, the incremental cost of building a second unit for test and monitoring is not that great, and you will have a source of spares, should your main unit have a failure. I am mostly looking for the 754 / 784 series but since the three digit series is not being built any more, it might be a good idea to collect this info and put in the files area for future reference.
