3-6 Programming Commands
DS335 Synthesized Function Generator
Setup Control Commands
*IDN? The *IDN common query returns the DS335's device configuration. This
string is in the format: StanfordResearchSystems,DS335,serial
number,version number. Where "serial number" is the five digit serial
number of the particular unit, and "version number" is the 3 digit firmware
version number.
*RCL i The *RCL command recalls stored setting number i, where i may range from
0 to 9. If the stored setting is corrupt or has never been stored an execution
error will be generated.
*RST The *RST common command resets the DS335 to its default configurations.
*SAV i The *SAV command saves the current instrument settings as setting number
i.
Status Reporting Commands
(See tables at the end of the Programming section for Status Byte definitions.)
*CLS The *CLS common command clears all status registers. This command
does not affect the status enable registers.
*ESE (?) i The *ESE command sets the standard event status byte enable register to
the decimal value i.
*ESR? {i} The *ESR common command reads the value of the standard event status
register. If the parameter i is present the value of bit i is returned (0 or 1).
Reading this register will clear it while reading bit i will clear just bit i.
*PSC (?) i The *PSC common command sets the value of the power-on status clear bit.
If i = 1 the power on status clear bit is set and all status registers and enable
registers are cleared on power up. If i = 0 the bit is cleared and the status
enable registers maintain their values at power down. This allows the
production of a service request at power up.
*SRE (?) i The *SRE common command sets the serial poll enable register to the
decimal value of the parameter i.
*STB? {i} The *STB? common query reads the value of the serial poll byte. If the
parameter i is present the value of bit i is returned (0 or 1). Reading this
register has no effect on its value as it is a summary of the other status
registers.
DENA (?) i The DENA command sets the DDS status enable register to the decimal
value i.
STAT? {i} The STAT? query reads the value of the DDS status byte. If the parameter i
is present the value of bit i is returned. Reading this register will clear it while
reading bit i will clear just bit i.
