To start with, you’ll place a signal source that generates IQ data (as complex numbers) on the flow graph. The signal generator block can actually generate too much data and slow down the CPU.

The output level can be calibrated–something not true of a lot of cheaper signal generators of the era. Signals produced can be modulated by an internal 400 Hz oscillator, or an external source.

Keysight’s new M9484C VXG signal generator enables customers to reduce test system setup complexity and achieve accurate and repeatable multi-channel measurements in a single instrument.

Figure 1 shows the new oscillator, based on CMOS 555 U1 in a feedback loop with RRIO (Rail-to-Rail Input-Output) op-amp integrator A2 generating a linear triangle output signal (Tout) with adjustable ...

Instead, they should have an adjustable top value and a separately adjustable bottom value: 5V and 0V, for example. The other day, I thought of a way to modify a conventional ‘diamond buffer’ (circuit ...
