Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 605

Emulated GPIB Name The GPIB name is the name given to a device used to

communicate with the instrument. Your instrument is shipped with gpib7 as its GPIB

name. The GPIB name is the same as the remote SICL address.

Emulated GPIB Logical Unit The logical unit number is a unique integer assigned to the

device to be controlled using SICL LAN. Your instrument is shipped with the logical unit

number set to 8.

This can’t be change, but you don’t care. Numbers 0 through 30, excluding 21, are valid

logical unit numbers for your instrument. Logical unit number 21 is used for the

instrument’s internal emulation mode. (If you are using Agilent VEE and SICL LAN, the

logical unit number is limited to the range of 0-8.)

Emulated GPIB Address The emulated GPIB address (bus address) is assigned to the

device to be controlled using SICL LAN. The instrument is shipped with the emulated GPIB

address set to 18. The emulated GPIB address, for N8201A, will always be 18, regardless

of what you set the GPIB address to.

The SICL LAN server uses the GPIB name, GPIB logical unit number, and GPIB address

configuration on the SICL LAN client to communicate with the client. You must match these

parameters exactly (including case) when you set up the SICL LAN client and server.

Configuring Your Instrument as a SICL LAN Server

After you have collected the required information from the SICL LAN client, perform the

following steps to set up your instrument as a SICL LAN server:

Identify the GPIB name.

1 Press System, Config I/O, SICL Server, Emulated GPIB Name, and notice that it is gpib7.

2 Notice that the Emulated GPIB Logical Unit is set to 8.

3 Notice that the Emulated GPIB Address is set to 18.
