10.1 GP-IB Interface Functions and Specifications
This instrument is equipped with a GP-IB interface in accordance with your preference.
This interface permits remote control from a controller such as a personal computer, and
output of various data.
Overview of the GP-IB Interface
The table below shows functions that are available in each mode.
Mode Function
Addressable mode Listener Functions performed by key operations (except for
LOCAL key and power ON/OFF) measured and
computed data output request setting parameters output
request error code output request
Talker measured and computed data output setting
parameters output, error code output, status byte output
Talk-only mode Talker measured and computed data output
Addressable Mode
This mode allows the WT210/WT230 to be controlled using commands from the
controller. The command system before the IEEE St’d 488.2 standard can be used.
The WT210/WT230 outputs data when a data output request command “OD” is
received. This mode allows data to be read at an arbitrary time.
488.2 Mode
Like the addressable mode, this mode allows the WT210/WT230 to be controlled
using commands from the controller. This mode allows commands conforming to the
IEEE St’d 488.2-1992 protocol to be used.
Talk-only Mode
This mode does not require a controller. Data is output at certain intervals. This
interval can be set to any length. This mode is useful when the instrument is
connected to a listener-only device such as a printer.
Print Mode
This mode is useful when harmonic measurement data are output to the external
plotter or external printer. For details, refer to section 9.9.
Note
Conventional power meters WT110, WT110E, WT130, WT200, WT1010, WT1030,
WT1030M, WT2010, and WT2030 supported addressable mode A and addressable mode B.
The WT210/WT230 supports addressable mode A.
