HRC Command Sequences

HRC-I Electronic Pulse Inject

Description:

This command sequence operates the electronic pulse calibration of the HRC-I. This is used to verify proper operation of each of the HRC charge amplifiers and the integrity of the wiring in the HRC-I Crossed-Grid Charge Detector (CGCD) which is used to determine x-ray event locations. The electronic pulse inject operates by applying pulses to the bottom electrode of the bottom MCP and relying on capacitive coupling to generate signals in the CGCD.

The sequence sets the calibration pulse amplitude to a value of PULSE_AMP and turns on the calibration mode. The HRC event processing electronics are then forced to use each coarse position along each axis as the center position of the event, pausing for DWELL_TIME at each forced position. After stepping through all amplifiers the calibration mode is turned off, the forced positions reset to zero, and the calibration pulse amplitude set to zero.

Cautions/Restrictions:

The HRC must be powered on (e.g. "Power Up HRC on CEA A"), initialized and the imaging detector selected for use (e.g. "Set HRC-I Unique Defaults").

The HRC-I MCP HV must be turned off before executing this sequence (see HRC-C-007).

Revision 1.6 1999/04/07 19:22:13 juda

HTML changes: added DOCTYPE and ALT reference for flow diagram - added "name"

tags to sub-sequenceschanged value for telemetry verifier 2CALPALV to reflect it as an analog readout

Revision 1.5 1999/03/03 20:37:25 juda

changed link for "Set HRC-I Unique Defaults" since filename has changed

Revision 1.4 1998/07/09 18:09:02 juda

converted to a generic sequence - pulse amplitude and dwell time are now variables (PULSE_AMP and DWELL_TIME) - removed second pass - marked as Approved

Revision 1.3 1998/07/08 20:25:01 juda

Fixed initial "Cal Mode Off" command to an "On" command - doubled sequence, first step through at amplitude 127 then repeat at 255

Revision 1.2 1998/07/01 19:08:15 juda

added lines to switch forced U and V axis positions back to 0
