7. CHECK for a pulse with a 1us width and with 0V and >4V levels on the oscilloscope.
5.3.8 External Modulation
Specification: 5 Vp-p for 100% AM modulation.
Procedure:
4 Connect the OUTPUT connector to the oscilloscope input using a 50 ohm coaxial cable and a
50 ohm feedthrough termination.
5 Set the unit to generate a SINE waveform with 1 KHz frequency and 5 Vp-p output.
6 Connect the external function generator to the MODULATION IN of the unit.
Use a coax cable with 50 ohm feedthrough termination.
4. Set the external function generator for a sine wave output with 400 Hz frequency and 3Vp-p
output.
5. On the unit select MODUL and then F1- AM, again F1- ON and then F4 - EXT
4 CHECK on the oscilloscope for an amplitude modulated waveform that is changing the
modulation depth by changing the external generator output amplitude.
5.3.10 RS232 Capability
1. Connect the waveform generator to a computer with RS232 capabilities.
4. Select RS232 remote operation mode on the UTIL menu and 19200 baud rate.
For more information on RS232 programming, see the Operation Manual, Section 4: Programming.
