How do I send binary data to an instrument using the Interactive Controller?

[Kent_N.]

In order to tune the frequncey on my Interference Analyzer it requires binary data to be sent (rather than ASCII characters". How do I send binary data using the ibwrt command or is there another command that I use to send binary data?

In the string that you give to interactive control, you can specify hexadecimal numbers by putting a '\x' in the string before the number. Each '\x' will allow you to put 1 byte of hexidecimal data after it.

Ex:

ibwrt "\x1e\x22\x35\x84"

Hope that helps you out.
