This subsystem is used to set the controls and parameters associate d
with the overall system communication . These functions are not related
to instrument performance.

:SYSTem : CO10tunicate :GPIB[1]I2I3I4[ :SELF] :ADDRess ?
Sets and queries the GPIB address .
NOTE
This command applies only to analyzers having Option A4H . Only on e
Option A4H can be installed in an instrument.
Factory Prese t
and *RST: It is set to 18 by : SYSTem : PRESet : PERSistent, which
sets the persistent state values to their factory defaults .
This command is persistent . The term persistent
means that the command retains the setting previously
selected, even through a power cycle .

Sets the hardware pacing scheme. This command is available only on
analyzers having Option 1AX . Only one Option 1AX can be installed i n
an instrument.
Off - holds the DTR line in the unasserted (off) conditio n
On - holds the DTR line in the asserted (on) condition
IBF ull - selects the input buffer full mode for the DTR line. The
IBFu1I parameter sets the DTR line to indicate when the device i s
ready to receive . When the number of received bytes in the inpu t
buffer of the device reaches the stop threshold, the device wil l
unassert the DTR line . When the number of bytes has been reduce d
to the start threshold, the device will assert DTR indicating that it
can receive input again . The device will also monitor the state o f
