» rtl_test -h
rtl_test, a benchmark tool for RTL2832 based DVB-T receivers

Usage:
	[-s samplerate (default: 2048000 Hz)]
	[-d device_index (default: 0)]
	[-t enable Elonics E4000 tuner benchmark]

As you can see, -t only works with E4000 tuners, and is meant to
determine the size of the L-Band gap this tuner has. The R820T2
you have doesn't have an L-Band gap, thus there is nothing to benchmark.

Regards,
Steve
