Hal,

The hp 59309A has a talk-only mode where timestamps are output at 40 Hz; so that would narrow it down to 25 ms.

BTW, if you're curious, look at the service manual (http://ko4bb.com/manuals.php). This is a pre-microprocessor age GPIB instrument that uses a 4096-bit ROM-based state machine (A5U2) as a CPU. Very clever, very 70's.

The 59309A is a wonderful, compact, vintage instrument, but my suggestion to the OP is that it's not really suitable for use for precise time or NTP.
