When you're comparing oscilloscopes and signal analyzers, the real decision usually comes down to where the measurement happens. Do you need a scope that can travel with you, or a device that pairs with a computer? The FNIRSI 2C53T and the Digilent Analog Discovery 2 are two dual-channel oscilloscopes that answer that question very differently. The FNIRSI is listed at USD 64.50, and the Digilent is listed at USD 150.00, an $85.50 spread.
Quick verdict: choose the FNIRSI for a more affordable, all-in-one approach; choose the Digilent for a software-rich, PC-connected workflow.

Product Notes
#### FNIRSI 2C53T
The FNIRSI 2C53T is a 50 MHz dual-channel digital oscilloscope with a built-in multimeter and signal generator, so one handheld unit covers several measurement jobs. That combination is the clear reason to choose it: instead of carrying a separate scope, multimeter, and generator, you can keep a single device in the field kit. The 50 MHz bandwidth is generous for the price point and gives you headroom for many audio, control, and basic electronics signals. The main limitation is the used condition. Because this listing is for a pre-owned unit, you should inspect the case, ports, and display before relying on it for important work. If you are comfortable with a used tool, the FNIRSI is a strong option for on-site signal analysis and quick checks.
#### Digilent Analog Discovery 2
The Digilent Analog Discovery 2 is a 30 MHz dual-channel digital oscilloscope with 14-bit resolution and 100 MSa/s sampling, and it ships with WaveForms 2015 software. The reason to choose it is the combination of resolution and software: 14 bits of waveform detail reveals finer signal variations, and WaveForms turns capture and analysis into a streamlined computer workflow. The limitations are the 30 MHz bandwidth and the need for a host computer via USB. It is not a standalone field instrument, so it works best within reach of a laptop or desktop. If you spend most of your measurement time at a bench, the Analog Discovery 2 makes the extra cost easy to justify.
Final Choice by Use Case
If your day includes moving from one machine to another, take the FNIRSI 2C53T with you. If you mostly work at a single bench with a computer nearby, the Digilent Analog Discovery 2 is the stronger fit. Pick the scope that matches your workspace, and the signal analysis part becomes much easier.
