.SH NAME
|
|
rtl_test \- a benchmark tool for RTL2832 based DVB-T receivers
|
|
.SH DESCRIPTION
|
|
Test tuning range and functional sample rates of your device
|
|
on your system.
|
|
Uses a re-purposed DVB-T receiver as a software defined
|
|
radio. Written for and incorporated into the osmocom rtl-sdr project.
|
|
.LP
|
|
Much software is available for the RTL2832. Most of the user-level
|
|
packages rely on the librtlsdr library which comes as part of the
|
|
rtl-sdr codebase. This codebase contains both the library itself and
|
|
also a number of command line tools such as rtl_test, rtl_sdr,
|
|
rtl_tcp, and rtl_fm. These command line tools use the library to test
|
|
for the existence of RTL2832 devices and to perform basic data
|
|
transfer functions to and from the device.
|
|
.LP
|
|
Because most of the RTL2832 devices are connected using USB, the
|
|
librtlsdr library depends on the libusb library to communicate with
|
|
the device.

.SH SYNOPSIS
|
|
.B rtl_test [OPTIONS]
|
|
.SH OPTIONS
|
|
.IP "-s samplerate (default: 2048000 Hz)"
|
|
.IP "-d device_index (default: 0)"
|
|
.IP "-t enable Elonics E4000 tuner benchmark]"
|
|
.IP "-p enable PPM error measurement"
|
|
.IP "-b output_block_size (default: 16 * 16384)"
|
|
.IP "-S force sync output (default: async)"
|
|
.SH EXAMPLES
|
|
.IP "To check the possible tuning range (may heavily vary by some MHz depending on device and temperature), call"
|
|
rtl_test -t
|
|
.IP "To check the maximum samplerate possible on your machine, type (change the rate down until no sample loss occurs):"
|
|
rtl_test -s 3.2e6
|
|
.LP
|
|
A samplerate of 2.4e6 is known to work even over tcp connections (see
|
|
rtl_tcp above). A sample rate of 2.88e6 may work without lost samples
|
|
but this may depend on your PC/Laptop's host interface.
