4. Low Pass Versus Bandpass Time domain low pass mode simulates traditional TDR measurements For this to work however the frequencies must be set at harmonic intervals This is done with SET FREQ Bandpass mode avoids this restriction but is limited to the impulse response The advantage of bandpass mode is that it allows time domain measure ments on highly frequency selective devices Gating The operator can place a time domain bandpass filter on the data which is called a gate In effect the analyzer will remove all responses received before the gate start time and after the gate stop time Gate Shape The analyzer allows the user to control the shape of the gate Minimum gate trades off rapid filter cutoff for less passband ripple 53 SYSTEM SEQUENCING MENU CONTINUE SEQUENCE LIMIT MENU TRANSFORM MENU FREQ RANGE 3GHzZ6GHz HARMONIC MEAS INSTRUMENT MODE SERVICE MEN TRANSFORM on OFF SET FREQ LOW PASS LOW PASS IMPULSE LOW PASS STEP BANDPASS WINDOW SPECIFY GATE RETURN 54 TRANSFORM WINDOW f MAXI on OFF MAXIMUM SET FREQ SETF NORMAL WINDNORM LOW PASS LOWPASS LOWPIMPU MINIMUM WINDMINI IMPULSE LOWPASS LOWPSTEP USE MEMORY WINDUSEMON STEP on OFF F WINDUSEMOFF BANDPASS BANDPASS DE ve OEMOOFF WINDOW AMPLITUDE DEMOAMPI SPECIFY PHASE DEMOPHAS GATE RETURN RETURN Turns on the transform and displays the time domain response of a linea
