[time-nuts] interesting oscillator setup.... Symmetricom

Hey All, I recently came into a few CO clock modules made by Symmetricom, Austron, etc. These were  Stratum 3E  level clocks. One of the modules can be seen here pictures 2,3,4 http://rescueelectronics.com/timeplot The  module ran in the position where the heatsink fins were vertical. The

[time-nuts] Morion MV89A position

Hello all, I have had a MV89A running now for a couple of years now.   It is inside of a Dewar along with bypassing capacitors and the adjustment pot. The end is sealed insulation.  For a matter of convenience the oscillator is mounted upside down. I am planning on reconfiguring the box it is

[time-nuts] Off topic project sort of heart rate monitor NEED BEATS PRE MINUTE TO ANALOG VOLTAGE

Hello Folks,   I am working on a project intended to convert an analog ECG signal to a voltage proportional the heart rate, The actual electrodes instrumentation amp is pretty much working fine  so no worries there.   The problem is, and here is where the relationship to time nut comes in. The

[time-nuts] Need usb time interval time for portable bullet chrongraph

Hello Folks I have been looking at bullet chrographs and wondering if I could get the a usb module to do a interval measurement and display on my laptop. on a yet to be discovered module to calculate the time interval between the pulses? The bullet travels at approx 1050 feet per second. By

[time-nuts] compensation for resistances value changes due to temp

Hello Folks,   I have one of these C-MAC Rakon Double oven oscillators. The oven and electronics run on a 12 vdc supply. For this I am using 2 stages of regulation, first to 18 volts and then to 12 vdc.  Both of these are 3 term regulators, I know not the best choice. But its a place to start.  I

[time-nuts] any HP 5370B Available or other TIC

Hello Folks, I am looking for an instrument that is better than Fluke 103a comparator. The purpose of this piece of equipment is help me learn more about oscillators and characterizing them   The HP5370B is the TIC I keep hearing about but I am not glued to that make or model. I wou;d like to

[time-nuts] frequency stabilty question

Folks,   I amtrying to understand some of the terms used here quite often. I quoted this from Wikipedia   An Allan deviation of 1.3×10−9 at observation time 1 s (i.e. τ = 1 s) should be interpreted as there being an instability in frequency between two observations a second apart with a relative

[time-nuts] Is anyone using Keithly 776 Freq counter TIC function?

Hello   I have a properly working Keithly 776 Frequency counter that has the TIC using the A and B inputs. I have z3801 that is considered my house reference, that 10 MHz output goes to the A input.   A double oven RAKON oscillator is connected to the is connected to the B input Both signals
