Self-Test Errors
The DS360 detected a problem with the CPU.
The DS360 detected a ROM checksum error. XX is the expected checksum
value.
The DS360 failed its RAM read / write test.
The calibration data in RAM is corrupted. The factory calibration data will be
reloaded from PROM.
DSP not responding. The instrument must be power cycled.
DSP data bus error. The message is followed by a six digit (hex) code,
corresonding to each data line (of 24) that is in error.
DSP address bus and memory cell error. The message is followed by a six digit
(hex) code, made up of three words.
Bits 0-15 are DSP address lines 0-15.
Bits 16-18 are set if there is an error on the X, Y or P memory spaces.
Bits 19-21 are set if there is an error in the low (D0-7), middle (D8-15) or high
(D16-23) bytes of the memory space.
This message displays an encoded version of the bits 0-3 of the test register (see
the *TST command).
Operational Messages
GPIB address. The value xx is the current GPIB address.
The Burst count has been adjusted to be lower then the current Rate count.
The digital output frequency has been adjusted to an allowable range after
changing the sampling frequency.
The amplitude and offset has been adjusted to an allowable value after changing
the source impedance.
The non-selected 2Tone amplitude has been adjusted to within a 1:1000 range of
the currently selected tone.
Tone 1 and Tone 2 amplitudes and offset have been adjusted to an allowable
value after changing the source impedance.
Tone 2 Frequency has been adjusted after the Tone 2 mode was changed to
squarewave.
RS232 baud rate. The value xxxx is the current baud rate.
Second selection of the CAL menu. If the calibration jumper is set correctly,
pressing any unit key will recall the default calbytes from PROM.
