BasicOperation35
• Mode:pulsemodesavailable:P/E(pulse‐echo),Dual,andThru(through‐
transmission)
• Pulser:Pulserwaveformsavailable:SpikeorSquare(tunablesquarewave)
• Freq:Pulsefrequency(squarewavepulsewidth)rangesfrom0.1 MHzto
20.00 MHz
TheSpikepulseisequivalenttoa20‐MHzsquarewavepulse.
2.2.4 Receiver
TheEPOCH 600standardreceiverfunctionsareaccessiblebyselectingtheRcvr
menu.Eachindividualreceiverparameter isdisplayedabovetheparameterkey s,and
canbeadjustedbypressingthecorresponding[P<n>]parameterkey.
ThefollowingreceiverparametersareavailableforliveadjustmentsintheRcvr
menu:

• Rect:Waveformrectification(Full[fullwave],Half+[halfwavepositive],Half–
[halfwavenegative],RF[norectification])
• Reject:Percentreject(from0%to80 %)
Theeightfiltersavailable onthe EPOCH 600allowbroadbandornarrowband
settingstomatchtherequirementsofagivenapplication.Eachisafullydigitalfilter
