Thermal3 Command
(requires ENG access)
bpd info

Description Displays beam-pointing driver information as follows:

BPD: Control Mode=<Control Mode>
BPD: Control State=<Control State>
BPD: Laser Mode=<Laser Mode>
BPD: Sensor Mode=<Sensor Mode>
BPD: DBPS Configuration=<DBPS Configuration>
BPD: Piezo Setpoint A=<Piezo Setpoint> Volts
BPD: Piezo Voltage A=<Piezo Voltage> Volts
BPD: Piezo Setpoint B=<Piezo Setpoint> Volts
BPD: Piezo Voltage B=<Piezo Voltage> Volts
BPD: Laser A Position=<DBP Position> um
BPD: Laser B Position=<DBP Position> um
BPD: Laser Centroid Position=<PSD Position> um

The beam-pointing control mode is set by the monitor commands bpd on (dual|a|b), bpd hold and bpd off. The beam-pointing control mode will be one of the following:
  • On
  • Monitor
  • Hold
  • Standby
  • Off

The beam-pointing control state is set by the monitor commands bpd on (dual|a|b), bpd hold and bpd off. The beam-pointing control state will be one of the following:
  • Init
  • On
  • Unstable
  • Error
  • Hold
  • Standby
  • Off

The beam-pointing laser mode is set by the monitor command bpd on (dual|a|b). The beam-pointing laser mode will be one of the following:
  • Dual
  • A
  • B

The sensor mode is set by the monitor command bpd sensormode [(norm|diff|psd)] and the NVS parameter bpd sensormode. The sensor mode will be one of the following:
  • Normal
  • Differential
  • PSD

The differential beam-pointing sensor configuration is set by the monitor command bpd dbpsconfig [(norm|rev)] and the NVS parameter bpd dbpsconfig. The differential beam-pointing sensor configuration will be one of the following:
  • Normal
  • Reversed

The piezo setpoint and the piezo voltage are set by the monitor commands bpd on (dual|a|b), bpd off and bpd drive [(dual|a|b) <voltage>].

The DBP position and the PSD position are calculated from the differential sensor and the PSD sensor.

Notes Thermal 1.0 / 1.7x equivalents:
  • The monitor command bpd info is comparable to head status bp.

Thermal 2 equivalents:
  • The monitor command bpd info is comparable to bpd info.
