DS335 Synthesized Function Generator

3-6 Programming Commands
Setup Control Commands
*IDN
*RCL i
*RST
*SAV i
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.
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.
The *RST common command resets the DS335 to its default configurations.
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
*ESE () i
*ESR {i}
*PSC () i
*SRE () i
*STB {i}
DENA () i
STAT {i}
The *CLS common command clears all status registers. This command
does not affect the status enable registers.
The *ESE command sets the standard event status byte enable register to
the decimal value 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.
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.
The *SRE common command sets the serial poll enable register to the
decimal value of the parameter 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.
The DENA command sets the DDS status enable register to the decimal
value 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.
