1) PRF/IFBW configuration : if one parameter is changed, the associated parameters will change accordingly.
a) Pulse Repetition Frequency (PRF) : set the frequency of the pulse generated by the pulse generator.
b) Pulse Repetition Interval (PRI) : set the pulse generation interval of the pulse generator.
c) Receiver IF bandwidth : set the intermediate frequency bandwidth of the analyzer, 1Hz to 10Hz.
d) Fixed PRF : if this item is selected, PRF will not change with the receiver bandwidth.
2) Modulation/Gates
a) Width : pulse width.
b) Delay : delay before pulse generation.
3) Duty Cycle: if [Calculate] is pressed, the duty cycle of the source and each reception channel will be
automatically calculated and displayed.
a) Pulse Mode ON/OFF : if this option is selected, the pulse function will be enabled.
b) Apply : if this button is pressed, all the configurations will take effect.
Attention
Setting of pulse duty ratio:
The prerequisite of narrow-band pulse calculation is to set the pulse duty ratio no more than 90%. But the
calculated pulse duty ratio may exceed 90%. In this case, the calculation result will prevail.
4.3 Pulse Envelope
Click the [Pulse Envelope] button in the [Pulse measurement] dialog box or click [View] > [Pulse Envelope] in
the menu to recall the [Pulse Envelope] dialog box. If this dialog box is gray and unavailable, select [Pulse Mode
ON/OFF] and click [Calculate] and [Apply] . The [Pulse envelope] dialog box is shown in Fig. 4.3.
