Introduction

After selecting the Experimental (PPG) Mode by pressing a button on the Custom Status page, the experimenter will need to review the parameters relevant to the selected Experimental (PPG) Mode.

Each of the Experimental (PPG) Modes is associated with a list of Mode Parameters. This parameter list is displayed on the Custom Parameters Page, which can be accessed from the Custom Status Page by any of the following:

• clicking the RunParams button at the top of the page
• clicking the same button used to select the PPG Mode
• clicking the link PPG/PSM Parameters

If the selected mode includes RF, the BNMR Mode Parameters#PSM Parameters will also be displayed on the Custom Parameters Page. When the run is stopped, the user may change these parameters as desired by clicking on a button or link. When the run is in progress, the parameter values are shown, but cannot be changed.

Examples of the Custom Parameter Page

PPG Mode 2e (run stopped)

Figure 1 shows the Custom Parameter Page for Experimental (PPG) Mode 2e. The run is stopped, and parameters may be entered by clicking on the appropriate link. PPG Mode 2e include RF, so the BNMR Mode Parameters#PSM Parameters as well as the BNMR Mode Parameters#Mode Parameters are shown. Note that in the PSM Parameters, Quadrature Modulation Mode is enabled, so that a number of extra parameters are shown. Compare with the PSM parameters for Mode 1f where Single Tone Mode is enabled.

PPG Mode 2e (run in progress)

Figure 2 shows the same page as Figure 1 except the run is now in progress. The parameter values are shown, but may not be changed. The run state window has changed from "Stopped" to "Running" and the Tune lines are not shown.

NOTE

PPG Mode 2e parameters can also be input graphically using the PPG Mode 2e Graphical page.

Features of the Custom Parameters page

Start/stop runs

Buttons at the top of the page allow the user to start and stop runs without returning to the custom status page.

Access to other MIDAS pages

Buttons at the top of the page give access to other MIDAS pages including the custom status page.

Timing Diagram link

an alias-link provides access to the Timing Diagram for the selected Experimental (PPG) Mode

Run status

A coloured box indicates the run status, e.g. Stopped, Running, Transition in progress.

Zaher's Calculator

A button near the top of the page give access to Zaher's calculator for conversion from bandwidth to pulse duration for the PSM

Mode 20 RF Setup page

For PPG Mode 20 only, a button near the top of the page gives access to the Mode 20 RF Setup page.

Mode 2e graphical page

For PPG Mode 2e only, a button at the top of the PPG Parameters Table gives access to the PPG Mode 2e Graphical page.

Read data/progress status line

This line gives the status of the asynchronous ODB data read and page update. This is mainly used for debugging.

Tunes line

Load, save, create a tune. See BNMR: Tunes for details.

Debug

Checkboxes at the bottom of the screen allow various debugging to be turned on.

• PSM debug - shows the values written to the PSM profile registers. To see this, scroll the page down.
• PPG debug - shows the "true" parameter values, i.e. the run parameter values written at the last "begin-of-run"
• Show PSM Gate Params - these are usually hidden as they are set to the default values
• Global debug - debugging for the Javascript. To see this, scroll the page down.

Programming Information

The Custom Parameters page is a MIDAS custom page. Custom pages must be listed in the /Custom ODB tree. Keys in this tree define the paths of the files containing external stylesheets, html and javascript code used by the bnmr and bnqr experiments. See Keys in /Custom ODB tree for details.

The Custom Parameters page and Custom Status page both use keys defined in the /Custom/hidden subtree for communication.
