T/R and Through Select
Selecting the “T/R” mode (also referred to as “Echo” mode) connects the T/R connector to the Receiver input.
This configures the instrument for performing Transmit/Receive measurements with a single transducer.
Selecting the “Through” mode connects the Through connector to the Receiver input. This configures the
instrument for performing Through measurements using a transmit transducer and a separate receiving
transducer.
Amplifier/Attenuator
This functional block provides control over the PureView receiver’s gain. The receiver gain can be set in 0.5dB
increments across the gain range of -11.5dB to +70db
.
Low Pass Filters
The low-pass filter enables a user to reduce the bandwidth of the PureView receiver to improve the signal to
noise ratio or to eliminate out-of-band signal content for applications that do not require the full receiver
bandwidth. Two user-selectable low-pass filter values are available.
High Pass Filters
The high-pass filter enables a user to eliminate low frequency energy from the PureView receiver signal, and
also to improve the rate at which the receiver output returns to its baseline level after the Pulser excites the
transducer. Two
user-selectable high pass filter values are available.
