1. Connect the device through the HPIB of the power supply HP6624A (HPIB) or whatever your power supply model may be.\u00a0 To check the hpib bus, go to shell as root:
\n\/opt\/hp3070\/bin\/btio -hpib -scan\u00a0\u00a0\u00a0 (this will tell you which HPIB exists, it should display your HP6624A or HP6621A).<\/p>\n<\/blockquote>\n

\n

2. cd \/dev and ls -al (this will show you all devices with their address in the system, look for 0x07??00 where ?? is the hex address of the device you need to set).
\nEx: 0x070800\u00a0\u00a0\u00a0 hp3488 (\/dev\/hp3488 has address of 08)<\/p>\n

3. If you want to install a device file yourself, make sure there’s no conflicting address.
\nEx: I have address 0c that’s not in the dev list and I like to create an hp8648c file for my HP8648C.
\nmknod \/dev\/hp8648c c 21 0x070c00 (0c is the address of the device HP8648C).
\nchmod 666 \/dev\/hp8648c (set permission for everyone)<\/p>\n

4. Checking to see if it does talk in BTbasic:
\nassign @HP8648C to “\/dev\/hp8648c” (make sure the device address is set at 12 decimal = 0c)
\noutput @HP8648C; “FREQ:CW 1550 MHZ;:FM:DEV .1KHZ”
\nyou should see the device operating at 1550MHZ with DEV of .1 KHZ.<\/p>\n
