IEEE 488 Operation
The Teseq Amplifiers can be operated remotely from a computer having an IEEE-488
interface. This interface allows the amplifier to be remotely controlled over the
General-Purpose Interface Bus (GPIB) by sending commands to the amplifier.
Additionally, amplifier status and forward and reverse power readings may be read
over the GPIB. All functions can be controlled by coded messages sent over the
interface bus via the 24-pin socket connector on the rear panel of the unit. The GPIB
command codes for the TESEQ Amplifier series are discussed on subsequent pages
and, for ease of identification; the command codes are identified within the text by bold
capital characters. For full information on the IEEE protocols and syntax the IEEE-
488.2 Standard should be consulted
.
When the amplifier receives a command over the GPIB, it automatically switches to
REMOTE operation, pressing the LOCAL key on the front panel returns the unit to
normal manual local operation. The initial state of the amplifier after power-on is the
full attenuation condition.

Note:
The ZEROATT command must be set in order for the amplifier to be able to
generate output power.
The GPIB address of the amplifier is set by via the Front panel using the touch screen
control button.

RS-232 Operation
For operation of the serial port a terminal application is required to be configured with
the following port configuration. Connect the RS232 cable and power the amplifier up.

Note:
To determine which COM port is being used for a specific protocol, navigate to
CONTROL PANEL
and double-click on the
SYSTEM
icon
.
Once under
System
Properties
, navigate to the
HARDWARE
tab and select
DEVICE MANAGER.
Scroll
down until you see
PORTS (COM & LPT)
and expand the drop-down menu. The
associated port should be listed.

Note:
Teseq
doesn’t recommend
the use of USB to serial adaptors unless the adaptor
contains an FTDI chip set.
