Instrument Control

Last Updated: June 19, 2009

The Instrument Control tab groups together the following functions:

  Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above.

Connection Panel

The Connection Panel makes the connection between the instrument part of the test set and the PC part. When the WLAN mode is started the instrument object is automatically created and only the Dispose button is active.

 

 

All functions are disabled until an instrument object is created and the settings panel is blank. Click Create if the instrument object has been Disposed.

 

SCPI Command: none

Autorange Panel

Autorange examines the transmitted signal from the DUT and configures the optimum settings for the Test Set to perform the DUT transmitter measurements. For Autorange to work the DUT must be transmitting a bursted signal. The DUT transmission frequency must also be entered in the Input control section of the Settings window.

SCPI Command: READ:ARANge?

Procedure Summary

  1. N4010: Click the appropriate button for your DUT:

  1. 11a/g for 802.11a,g OFDM devices

  2. 11b for 802.11b DSSS devices

  3. 11n/20MHz for 802.11n 20 MHz bandwidth signals

  4. 11n/40MHz for 802.11n 40 MHz bandwidth signals

A difference in output levels between the transmitters of a single 802.11n DUT can exist. If you intend to perform measurements on more than one DUT transmitter it is advisable to measure all the DUT transmitters and examine the differences.

Different Power Range values may be required for different DUT transmitters to ensure that neither input overload nor lack of dynamic range conditions occur.
