Some time ago I have bought a small but reliable device named OSA103mini. This one is a contemporary all-in-one device allowing you:
- watch the form of signals up to 200 MHz in real time or up to 10 GHz in stroboscopic mode.
- generate signals up to 50 MHz (with the unevenness of the amplitude-frequency characteristic less than 0.5 dB).
- measure frequency (8 digits)
- analyze the specter (using FFT, up to 1 GHz)
- VNA
- LC meter
- SDR transceiver
