LIA STATUS BYTE bit name usage
0 INPUT/RESRV Set when an Input or Amplifier overload is
detected.
1 FILTR Set when a Time Constant filter overload is
detected.
2 OUTPT Set when an Output overload is detected.
3 UNLK Set when a reference unlock is detected.
4 RANGE Set when the detection frequency switches
ranges (harmonic x ref. frequency decreases
below 199.21 Hz or increases above
203.12 Hz). Time constants above 30 s and
Synchronous filtering are turned off in the upper
frequency range.
5 TC Set when the time constant is changed indirect-
ly, either by changing frequency range, dynamic
reserve, filter slope or expand.
6 TRIG Set when data storage is triggered. Only if sam-
ples or scans are in externally triggered mode.
7 unused
The LIA Status bits stay set until cleared by reading or by the ❊CLS command.
ERROR STATUS BYTE bit name usage
0 Unused
1 Backup Error Set at power up when the battery backup has
failed.
2 RAM Error Set when the RAM Memory test finds an error.
3 Unused
4 ROM Error Set when the ROM Memory test finds an error.
5 GPIB Error Set when GPIB fast data transfer mode aborted.
6 DSP Error Set when the DSP test finds an error.
7 Math Error Set when an internal math error occurs.
The Error Status bits stay set until cleared by reading or by the ❊CLS command.
