Agilent Blackbody Controller Setpoint Powerup State Configuration

This procedure sets the powerup voltage setpoints provided by the Agilent to the blackbody controller boards.

Setting the powerup setpoints to a non-zero value can prevent ABB/HBB runaway issues, in the case that the AERI is powered ON but FTSW is not invoked.

If using web interface:
  1. Open http://169.254.44.52 in a web browser
  2. From the Welcome Page, click Browser Web Control tab on left
    • May need to allow Java exeptions: Run this time, Update later, Run
    • Scroll down to see Channel 1006 & 1007.  May need to expand window to reveal second hidden scroll bar for this
  3. Click Allow Full Control
  4. Click Commands… button and command interface window will open.  Enter commands as follows:
  5. Verify auto recall is set to 1 (ON):   mem:stat:rec:auto?  <Write & Read>
  6. Verify state to recall is set to +2:   mem:stat:rec:sel? <Write & Read>
  7. Record the value of Channel 1006; this is the HBB set point; usually 0.894 for 60 deg C
  8. Reset instrument to power on state: *rcl 2 <Write>
  9. If Channel 1006 or 1007 now reads 0, there is risk of HBB or ABB runaway
  10. Use Configure Channel… to change 1006 to match HBB set point noted above (usually 0.894), and 1007 (ABB set point) to 4.986 (no heating).
  11. Save revised power on state:  *sav 2 <Write>
  12. To verify changes, reset and recall:  *rst <Write>, *rcl 2 <Write>, confirm channel settings.

If using telnet or putty instead of web interface, the same commands apply, along with:
  • To query channel 1006/1007: SOURCE:VOLT:LEV? (@1007)
  • To set channel 1006/1007: SOURCE:VOLT:LEV 4.986,(@1007)
