[time-nuts] Re: Instruments for 1PPS accuracy measurement

[Pavel Kořenský]

Hello,

it depends if you have time/frequency as a hobby or if you plan to do 
some serious science/business on this field.
At the amateur/hobby level, you can buy something like TinyPFA 
(https://www.tinydevices.org/wiki/pmwiki.php?n=TinyPFA.Homepage) and/or 
used HP 53132A Time Interval Counter on EBay for couple of hundreds USD.

For more serious business, there are things like Microchip 53100A 
(https://www.microsemi.com/product-directory/phase-noise-and-allan-deviation-testers/5565-53100a) 
and/or Keysight 53230A 
(https://www.keysight.com/us/en/assets/7018-02642/data-sheets/5990-6283.pdf) 
but the price is couple of thousands USD.

I am amateur, so I am using TinyPFA and old but reliable Agilent 53132A. 
Both instruments I am using together with TimeLab software (free sw).

Best regards
PavelK

It would be appreciated if the price and lead time of each instrument is provided, as well.Thank you for helping me.
