Ji Jerry,
The Fluke exhibit a 100ps resolution whereas the SR620 has 25ps.
This is the main difference I see from datasheets.
cheers

How does the Fluke PM6690 (same as Pendulum CNT-90) compare to the
SR620? A neighbor is selling one in perfect condition (per him) for
$900

Hi,
I've ordered a SR620 with the option 01 (higher stability standard)
Should be there in August Thanks Stephane

Re: [time-nuts] buying a time interval counter
Hi Stephane:
I traded my HP 53132A counter for an SR 620. The 53132 has what I'd
call a user hostile interface, so if you are manually controlling the
counter the SR 620 has a huge advantage.
I also like the long display on the 620 which can be read from across
the room.
PS Stanford Research is a company founded by physicists and makes some
really high quality stuff. In fact some of the products
HP/Agilent/Keysight sells are repackaged SR instruments.

The claim to fame for the HP 53132A is that it can make a frequency
(not time interval) measurement to 1E12 in a second. Here's how to
get
that same result with the SR620:

On the down side the printing functions on the 620 require an Epsom
printer. Does anyone have a solution for that?
PS SR also makes a 10 MHz crystal oscillator that has options trading
stability for aging as well as the EFC tuning polarity and range so as
to match other OCXOs.

At one point they were looking into making a GPS time receiver where
the cable length calibration would be built-in.

Hello there,
I'm planning to buy a such instrument in order to do some frequency
stability measurement at work. The SR620 seems to be discontinued.
What model still distributed would you think is good for that at the
moment ?
Thanks & cheers
Stephane
