option string, the data string, and finally the unit string. If the program sequence is not correct or the string
does not match the corresponding functionality, although the instrument executes the code and does not give
any error notice, the result may be wrong. For example, set the frequency of the channel A at 100 kHz, remote
command: 100:AFREQ:kHz:100. This is a string in wrong sequence. Another example, select the No.3
waveform of channel B, remote command: CHA:BWAVE:3No., the command and function are not matching.
4.6.3 Application Example
The application examples of the variety type of the remote command are shown as followings. (No blanks in the
command)
Example1: Channel A, single output, frequency at 1MHz
RS232 mode: 88CHA:AFREQ:1:MHz
USB mode: CHA:AFREQ:1:MHz
Example 2: Channel B, single output, frequency at 1 kHz
RS232 mode: 88CHB:BFREQ:1:kHz
USB mode: CHB:BFREQ:1:kHz
Example 3: Channel A, single output, pulse wave, duty cycle at 25%.
RS232 mode: 88CHA:ADUTY:25%
USB mode: CHA:ADUTY:25%
Example 4: Frequency sweep output, start frequency at 1 kHz.
RS232 mode: 88FSWP:STARF:1:kHz
USB mode: FSWP:STARF:1:kHz
