I have here TLS216.
Yes, it has 500Mhz Bandwidth., verified.
But ,obviously, no potocool decoding.
TLS216 is really sluggish by operation.
16 ch and 2Gs/s at all channel, it is possible, because Tek has using four TDS640 acquisition chipset (one Chipset = 4 channel).
But TDS640 has a big disadvantage: No peak dectet-acquisition, high WFM/s-Acquisition is impossible.
Reason: TDS640 ADC is CCD-based, 2 Gs/s-CCD and 10Ms/s ADC. To much dead times.
Many TLS216 has problem with bad SMD capacitor. My TLS216 is very late TLS216 with TDS700A-CPU Board without capacitor issues, but old firmware(V1.0.3e).
