Why does my function generator amplitude not match the set point?

March 3, 2020

The most likely cause is that the generator output is not configured with the correct value that matches the actual load. Function generators like the SIGLENT SDG series are designed to have an output impedance of 50 ohms. This output impedance is assumed to be in series with a known load impedance R2, as shown … Continued

How to activate the SDG sweep marker function

May 31, 2019

The SIGLENT SDG6X series of arbitrary waveform generators feature a frequency marker function that will output a signal when the sweep output passes through a user-defined target frequency. This can be very helpful when synchronizing measurements with other instrumentation, like oscilloscopes, that have no other way of syncing up with the frequency sweep. To activate … Continued

SDG1X firmware adds TrueArb capability

May 14, 2019

Starting at firmware version, the SIGLENT SDG1000X series of arbitrary waveform generators now feature TrueArb output capability. Traditional arbitrary waveform generators use DDS (direct digital synthesis) to create waveforms. This technique is very powerful, but at higher output frequencies, DDS begins to lose resolution because it will skip or drop output samples in order … Continued

SIGLENT SPA1010 Amplifier output control

January 15, 2019

The SIGLENT SPA1010 Amplifier can be a useful accessory for applications requiring higher voltage and/or current from a signal source like a SIGLENT SDG arbitrary waveform generator. The SPA features a power-on indicator LED, Short LED, a X10 indicator LED, and a set of switches on the front panel. To use: Connect the output of … Continued

Programmatically selecting a built-in arbitrary waveform with an SDG

January 3, 2019

The SDG series of arbitrary waveform generators have a number of built-in arbitrary waveforms including health-related waveforms like cardiac and math waveforms like sinc. To read the available waveforms, you can send the following string: STL? This will return a list similar to the following (the exact return data depends on the instrument model and firmware … Continued
