Receiver Controls in JSR .Net Control Panel
Power LED
User selectable as a constantly-on power indicator or as a blinking indicator (to identify one PureView
unit from among multiple units in a multi-unit system).
Receiver Mode
This control selects the source for the Receiver’s input signal as either Pulse Echo (selects the T/R
connector) or Through (selects the Through connector).
Gain
This allows a user to select the Receiver gain from -11.5dB to +70dB in steps of 0.5dB.
Low Pass Filter
This control selects either of the Receiver’s two low-pass filter values. Depending on the PureView
model, the low-pass filters may have values of 150MHz, 300MHz, 500MHz, or other values.
High Pass Filter
This control selects either of the Receiver’s two high-pass filter values. Depending on the PureView
model, the high-pass filters may have values of 1MHz, 5MHz, 30MHz, 65MHz, or other values.
Pulser Controls in JSR .Net Control Panel
Trigger Enable
This control allows a user to enable or disable the Pulser from responding to trigger signals.
Trigger Source
This control selects either Internal or External modes of pulser triggering.
For Internal triggering, the pulser is triggered at the rate set by the PRF control that is described
below. A positive-going Sync pulse is produced on the Trig / Sync connector in synchronization
with the pulser firing.
For External triggering, the pulser is triggered by the rising edge of a Trigger Input Signal applied to
the Trig / Sync connector.
If the trigger rate exceeds the maximum pulse repetition frequency (PRF) for the PureView model,
the amplitude of the transducer excitation pulse (on the T/R connector) may be reduced.
PRF
The Pulse Repetition Frequency (PRF) sets the rate of pulser firing rate when a PureView unit is set for
internal trigger mode. The range of PRF values available is dependent on the PureView model.
