Command system EN SOURce :MOD:QPSKey:INTernal:RATE |MINimum|MAXimum SOURce :MOD:QPSKey:INTernal:RATE? [MINimum|MAXimum] Function description Sets the rate at which the output phase "moves" between the carrier and offset phase. Argument Instructions The internal modulated waveform is a square wave with a duty cycle of 50%. Return format Return as a scientific count. Example SOURce1:MOD:QPSKey:INTernal:RATE 200 /* Set the modulation rate for channel 1 QPSK modulation to 200Hz */ 3.22.2 SOURce :MOD:QPSKey:PHASe Command format SOURce :MOD:QPSKey:PHASe1 |MINimum|MAXimum SOURce :MOD:QPSKey:PHASe1?
