Quantum QTM300CA - Manual (Page 6)

The status bar at the bottom shows the serial port and connection status.
Possibilities are:
Serial Port Status: - Off Line
- COM1: 57600 N 8 1
- COM2: 57600 N 8 1
Connection Status: - Status: Clone connected
- Status: Clone & QT300 connected
- Status: Clone & QT310 connected
- Status: Clone & QT320 connected
- Status: No Clone
Status Bar
Display
Allows you to enter the expected chip supply voltage and the burst length (total of both
channels together in the case of the QT320) in order to allow Guideline boxes to show
reasonably accurate timing values. The QTM300CA cannot measure these parameters.
To measure the burst length, use an oscilloscope with a 750K series resistor on the
probe tip to limit loading, and measure on either SNS pin of the QT chip from the start
of the first pulse to the end of the last.
QT320: Add together the burst length times of both channels when entering the number
for this chip.

Entry
These boxes show and modify the available Setups for the chosen chip.
Timing related values have no meaningful unit of measure unless interpreted together
with the device supply voltage and Sleep Cycles. To aid in understanding the effects of
these Setups, ‘Guideline’ boxes are used next to timing related Setups to give an
estimate of the result in seconds.
Guideline boxes cannot be modified, they only exist to inform you of the effects of the
timing Setups. Guideline numbers will change if Sleep Cycles, Burst Length, or Voltage
are changed, because QT3xx device timings vary with these things.
The QTM300CA and QT3View cannot directly measure the effects of Setup changes or
supply voltage changes. The numbers presented are reasonable estimates only.
