Common
Commands and
Queries
The commands are presented exactly as they should be typed in
your program. Optional nodes were omitted from these commands.
Factory defaults after *RST or front panel reset are shown in bold
typeface. Parameter low and high limits are given where
applicable.
Command and Parameters
PHASe2:LOCK {OFF | ON}
PHASe2:ADJust <value>
PHASe2:FINE <value>
PHAS2:FINE adjustment is always relative to the PHAS2:ADJ
setting.
For instance, Programming PHAS2:ADJ 120 and
PHAS2:FINE -1.55 will generate a phase offset of 118.45 degrees.
Note that the PLL lock range depends on the number of waveform
samples, sampling frequency and external reference frequency.
The relationship between these parameters is show in Appendix
A.
The system-related commands are not related directly to waveform
generation but are an important part of operating the Model 3152.
These commands can reset or test the instrument, or query the
instrument for system information.
Command and Parameters

SYSTem:VERSion?

TEST?
*TST?
*IDN?
*OPT?
Since most instruments and devices in an ATE system use similar
commands which perform similar functions, the IEEE-STD-488.2
document has specified a common set of commands and queries
which all compatible devices must use. This avoids situations
where devices from various manufacturers use different sets of
commands to enable functions and report status. The IEEE-STD-
488.2 treats common commands and queries as device dependent
commands. For example, *TRG is sent over the bus to trigger the
instrument. Some common commands and queries are optional,
but most of them are mandatory.
