Calculating Output Amplitude Accuracy using dB

October 1, 2018

Some specifications, like the SDG800 and 1000 series, describe the vertical accuracy using dB The SDG1000, for example, states: Vertical Accuracy = ± (0.3 dB + 1 mV) First, let’s convert the dB part… Vertical Accuracy(dB) = 20 log (1 + (Error(%)/100)) ±0.3 dB = 20 log (1 + (Error(%)/100)) Error (%) = 3.5% So, … Continued

Create an arbitrary waveform using Coordinate Mode with EasyWave software

August 24, 2018

There are a number of ways to create waveforms for arbitrary generators. The correct method depends on: The number of segments of the waveform? Required precision of the location of each sample? Complexity of the waveform? Is it a number of pulses or a number of complex curves/small details? For sequences of pulses/square waves or to … Continued

March 1, 2018

The SIGLENT SDG6000X series of Arbitrary Waveform Generators (AWG) have the ability to source IQ  modulated waveforms with the option SDG6000X-IQ. To activate the IQ  capabilities: Purchase the SDG6000X-IQ option from your nearest SIGLENT Authorized distributor or direct office. Follow the directions to create an activation code. 2. Power on the generator and press the Waveforms … Continued

Format for programmatically building an Arbitrary Waveform for SDGs

February 26, 2018

The SDGs require UTF8 formatting for the words used to build an arbitrary waveform. The code may report “UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0x80 in position 77: ordinal not in range(128)” This indicates that the arbitrary waveform data is coded as “ascii” which is not the expected data format “utf8”. Here is the proper … Continued
