Wednesday, March 12, 2014: A signal generator, also known as a function generator or an arbitrary waveform generator, is a type of signal source. Technology has evolved tremendously to impact the performance, accuracy and ease of use of these devices. Starting from the vintage tube device, followed by the arrival and integration of microprocessor technology, to the current new generation of synthesised function generators, these devices have evolved with time and changing requirements.
Model: N5183B MXG/ N5173B EXG, Brand: Agilent Technologies, Manufacturer: Agilent Technologies
Launched in December 2013, the new N5183B MXG and N5173B EXG microwave analogue signal generators provide important alternatives in size, speed and cost. They provide enhanced performance in phase noise, output power and frequency-switching speed.
Key features
N5183B MXG
-
Offers accuracy, efficiency and near-PSG performance
-
Phase noise of less than -124 dBc/Hz and -75 dBc spurious enables module and system level testing up to 40 GHz
N5173B EXG
-
Offers a combination of output power (+20 dBm at 20 GHz) and low harmonics (<-55 dBc)
-
Supports continuous-wave (CW) blocking for receiver testing or basic local-oscillator upconversion for point-to-point microwave backhaul links
