5-128 Status Word Definitions
SR785 Dynamic Signal Analyzer
Input Status Word
Bit Name Set when
0 LOW1 Input1 has fallen below half full scale
1 HLF1 Input1 has exceeded half full scale
2 OVL1 Input1 has exceeded full scale
3 HIV1 Input1 has exceeded 35 dBV
Input range switched to 34 dBV.
4 ARG1 Input1 has AutoRanged
5-7 unused
8
LOW2 Input2 has fallen below half full scale
9 HLF2 Input2 has exceeded half full scale
10 OVL2 Input2 has exceeded full scale
11 HIV2 Input2 has exceeded 35 dBV.
Input range switched to 34 dBV.
12 ARG2 Input2 has AutoRanged
13-15 unused
These status bits do not necessarily reflect the current input status. The Input
status bits stay set until read by INPS?. They are also cleared by the *CLS
command. Use INPE to set bits in the Input status enable register.
To read the current input overload condition, use INPC?.
Error Status Word
Bit Name Set when
0 OUTE An output error has occurred
(Print, Plot or Dump)
1 DSKE A disk error has occurred
2 FLTE A math error has occurred
3 RAME RAM memory test fails
4 ROME ROM memory test fails
5 VIDE Video memory test fails
6 HELPE Help memory test fails
7 DSDE DSP data memory test fails
8 DSPE DSP program memory test fails
9 DSRE DSP DRAM memory test fails
10 CAL0 DSP calibration memory fails
11 CAL1 Ch1 calibration memory fails
12 CAL2 Ch2 calibration memory fails
13-15 unused
The Error status bits stay set until read by ERRS?. They are also cleared by the
*CLS command. Use ERRE to set bits in the Error status enable register.
Bits 7-12 are set by the power on tests. Bits 3-5 are set in the
[System]<Diagnostics>.
