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

Display

Allows you to dial in 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 from the start of the first pulse to the end of the

last. Add together the burst lengths of both channels when entering the number for the

QT320.

These 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.
