Greetings,
I am trying to communicate with 7265 lockin amplifier from signal recovery via RS232 interface. Here are the main problems that I am facing.
1) I have set internal oscillator frequency to 1000Hz. However, when i try to read it using FRQ[.] command, the response is 10^6 Hz which is 1000 times larger than the set frequency. Also, the lockin loses connection while communicating with the computer as you can see in the attached file. I have tried changing the RS 232 cable as well but still it doesn't resolve the issue.
2) Even if I try a simple code such as ID, although the instrument responds with 7265, it still loses communication with the computer and intermittently return 0 as value. Please help regarding the same.
