Hmm, sounds like a handshaking problem of some sort. Are you using the MR command to synchronize your readings?
This code is from my 5370B console app that reads a single frequency value: ------------snip-------- void main(S32 argc, C8 **argv) { if (argc < 2) { printf("Usage: 5370B <address>\n"); exit(1); } GPIB_connect(atoi(argv[1]), GPIB_error, 0, 3000); // 3-second timeout GPIB_set_EOS_mode(10); // Incoming strings terminated by ASCII 10 (LF) GPIB_write("FN3GT3MD2"); // Frequency function, 0.1 second gate time, hold until MR command issued GPIB_write("MR"); // Issue Manual Rate command to enable reading printf("%s",GPIB_read_ASC()); GPIB_disconnect(); } -----------end snip-------- -- john, KE5FX > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Jim Palfreyman > Sent: Saturday, June 21, 2008 5:42 PM > To: time-nuts@febo.com > Subject: [time-nuts] 5370B and GPIB > > > Hi folks, > > Well I'm now trying to get my 5370B talking via GPIB so I can capture > data.
