6.2 Programmed Port and Configuration of Instrument
625
6.1.6 Programming Precautions
1) Initialize the instrument status before changing the setting.
For instrument setting of remote control, initialize the instrument status (sending ―*RST‖, etc.) and then set
the required status.
2) Command sequence
Generally, the setting command and query command should be transmitted separately. Otherwise, the returned
value of the query command will change according to the current instrument operation sequence.
3) Fault response
The service request must be sent by the instrument. The controller of the test system should be programmed to
guide the instrument to actively send the service request if required, so as to enable the corresponding service
interruption program.
4) Error queue
The error queue instead of the status register should be inquired once the service request is processed by the
controller program, so as to find more accurate causes. The queue should be always inquired in the controller
program test phase to obtain the commands sent by the controller to the instrument.

6.2.1 LAN
The programmed LAN (Local Area Network) system is configured with SOCKET to control 4051
signal/spectrum analyzer.
Caution
Use of USB master control port connector of the front panel:
The Type-A connector of the front panel is a USB master control port connector. In the 4051signal/spectrum
analyzer, this port is connected to the flash disc with USB1.1 interface to update the software in the
instrument. It can also be connected to the USB keyboard and mouse to control the signal/spectrum analyzer.
However, this port cannot be used for remotely control the instrument. However, this port cannot be used for

6.2.1.1 Establish Connection
Connect the 4051 series signal/spectrum analyzer and external controller (computer) to LAN through cables.
Pay special attention to the possibility of conflict caused by IP address setting and confirm with the network
administrator before setting to prevent any conflict.
6.2.1.2 Interface Configuration
Ensure that the physical connection is smooth for remote control of the signal/spectrum analyzer by LAN. As
the DHCP, domain name access and WAN are not supported, the network programming of the
signal/spectrum analyzer is relatively simple. Users only need to press
