Specifications

3-22 Operation
DS360 Ultra Low Distortion Function Generator
value.The DS360 is configured to send or receive: 2 stop bits, 8 data bits and no parity
bits.When data is being recieved by the DS360, the ACT LED will flash. If this LED is
not flashing there is no data being recieved by the DS360.
When connecting the DS360 to a PC use a standard PC serial cable, not a “null modem”
cable. The DS360 is a DCE (Data Communications Equipment) device, and should be
connected with a straight cable to a DTE device (Data Terminal Equipment). The
“minimum” cable needs pins 2, 3 and 7. For hardware handshaking, pins 5 and 20 (CTS
and DTR) should also be passed. Occasionally pins 6 and 8 (DSR and CD) will be
needed; these lines are always asserted by the DS360.
Error Messages
The DS360 has two types of error messages, operational error messages and self test
error messages. Operational errors include entering out of range values or incorrect units.
Self test error messages only occur when the unit is running its internal self tests.
Operational Errors
Message Meaning
AC-DC ER The Vac+|Vdc| value exceeded the limit for the current setting.
AC ERR The amplitude entered is out of the allowable range.
BUR.RAT.ER Burst Rate Error. Burst Count > Rate Count.
NO.Cal.JPR No Cal jumper. Calbyte cannot be written without setting the calibration jumper.
NOT APPL The parameter is not applicable to the current instrument setting.
OFF ERR The offset entered is out of the allowable range.
OUTQ ERR Output queue error. The output queue is full.
RANGE ER The value entered is out of the allowed range for the current parameter.
RCL ERR Memory error found on power up or when recalling a stored setting. (Also
occurs when recalling a setting that hasn’t been previously stored)
SYN ERR The command syntax is invalid.
TOUT ERR Time out error when writing DSP memory.
UNITS ER The units set with AMPL, T1AA, T2BA or DPTH commands are not allowable
or nonexistent.
