To Output FSK Modulated Waveform

Requirement

Use the SCPI commands to realize the following functions:

Output FSK modulated waveform from the output connector of CH1 at the front panel; set the carrier

waveform to sine (1kHz frequency, 5Vpp amplitude, 0V

DC

offset voltage and 0° start phase); select external

modulation source; set the hop frequency to 2kHz and the modulation polarity to positive.

Method

1. *IDN?

/*Query the ID string of the signal generator to check whether

the remote communication is normal*/

2. :SOUR1:APPL:SIN 1000,5,0,0

/*Set the waveform of CH1 to sine, the frequency to 1kHz, the

amplitude to 5Vpp, the offset to 0V

DC

and the start phase to

0°*/

3. :SOUR1:FSK:STAT ON

/*Turn on the FSK modulation function of CH1*/

4. :SOUR1:FSK:SOUR EXT

/*Set the FSK modulation source of CH1 to external */

5. :SOUR1:FSK 2000

/*Set the FSK hop frequency of CH1 to 2kHz */

6. :SOUR1:FSK:POL POS

/*Set the FSK modulation polarity of CH1 to positive */

7. :OUTP1 ON

/*Turn on the output of CH1*/
