8. The

Reset Zoom

button resets the axes in the

Graph

to their standard values.

9. The

Interlock

indicator displays

when the interlock is correctly connected, and

when discon-

nected.

10. The

Ce:YAG Temp

indicator displays the temperature of the

Ce:YAG source

in real time. This indicator will only

appear when a

Ce:YAG driver

is connected to the computer. Should the temperature be too high the temperature

will appear in

red

. Should the temperature be too low, the temperature will appear in

blue

.

4.1.3 Experiment View

The

Experiment View

box is used to display information related to the usage of each channel. This section allows limited

control of the light source while it is active.

Figure 4.13:

Experiment View, Light Source Channel

1. The

Light Source Channel

box (Fig.

4.13

contains all elements related to a single light source channel.

2. The

Scope Channel

box (Fig.

4.14

is used to control and configure an active

Scope

.

Figure 4.14:

Experiment View, Scope Channel

3. The

Controls View

displays all elements to control/configure the channel.

a) The

Start/Stop

button activates/deactivates the light source connected to the

Light Source Channel

.

b) The

Edit

button opens the

Channel configuration

window to edit the pulse sequence. This button is only

accessible when the channel is deactivated.

c) The

Current Box

box allows the current to be changed exactly (in mA).

d) The

Current Slider

allows the light source current to be adjusted.

e) The

Status

box displays the status of the channel (

Light source

or

Scope

). The

Status

will display

RUN-

NING...

when active and

STOPPED

when deactivated.
