Thanks for that info--I feel better now about my setup! Any idea when the next release will be out? Regards, Stan -----Original Message----- At 33 seconds past the minute Heather requests the SYST:STATUS? info from SCPI receivers which takes 3 seconds for the device to send. The clock does not update while Heather is reading the status info because the receiver is not sending any time messages. The next release "fakes" the missing seconds so the clocks appear to keep ticking even though the receiver is not sending time codes. ------------------------------
