Use binary data format instead of ASCII Minimize the number of GPIB transactions. Avoid unnecessary use of *RST. Put ADC Ranging in Bypass for FFT Measurements Minimize DUT/instrument setup changes. Consider using LAN instead of GPIB. Using an Option Mode: Minimize the number of GPIB transactions. Using an Option Mode: Avoid automatic attenuator setting. Using an Option Mode: Optimize your GSM output RF spectrum switching measurement. Using an Option Mode: Avoid using RFBurst trigger for single burst signals.
