8. Sweep frequency limits are now set. Select the desired 3i
main generator mode using the GEN MODE switch.
Notice that the generator frequency will sweep or step
between the two limits when CONT SWP, TRIG SWP, 4.
SWP HOLD or SINGLE STEP is selected.
Connect a repetitive signal (see Trigger Input specifi-
cation, Paragraph 1.2.9) to TRIG IN connector.
Adjust the TRIG LEVEL control for proper triggering.
5. The main generator will sweep from the start frequency
9. Select the desired SWEEP/STEP TIME. to the stop frequency and reset back to start frequency
for every cycle of the TRIG IN signal. However, if the
2.5.6 Operation as a Continuous Sweep Generator trigger rate is faster than the sweep rate, the sweep
generator will neglect all trigger signals during each

6. Set the TRIG LEVEL control to full ccw if manual
2: Set the GEN MODE switch to CONT SWP. triggering is desired and operate the MAN TRIG
switch for each cycle of sweep.
3. The proper waveform outputs at SWEEP OUT and
GCV OUT are shown in Figure 2-9. 2.5.8 Operation as a Sweep and Hold Generator
2.5.7 Operation as a Trigger Sweep Generator 1: Select the desired SWEEP MODE switch setting and set
up the sweep frequency limit as in Paragraph 2.5.5.2.
Ue Select the desired SWEEP MODE switch setting and set
up the sweep frequency limit as in Paragraph 2.5.5.2. 2. Set the GEN MODE switch to SWP HOLD.
2 Set the GEN MODE switch to TRIG SWP.
