From 40f93c2ae1c2c9a6e726cdb377dc248fdcef646b Mon Sep 17 00:00:00 2001 From: Jon Szymaniak Date: Sun, 16 Feb 2014 00:11:30 -0500 Subject: bladeRF: RXVGA2 range is [0, 30] While the RXVGA2 gain can technically go up to 60 dB, the LMS6002D datasheet recommends it be clamped to 30dB. libbladeRF clamps to a max of 30dB, so there's no use in setting max to 60 dB here. --- lib/bladerf/bladerf_source_c.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/bladerf/bladerf_source_c.cc b/lib/bladerf/bladerf_source_c.cc index 1017dcf..96ba94d 100644 --- a/lib/bladerf/bladerf_source_c.cc +++ b/lib/bladerf/bladerf_source_c.cc @@ -140,7 +140,7 @@ bladerf_source_c::bladerf_source_c (const std::string &args) _vga1_range = osmosdr::gain_range_t( 5, 30, 1 ); /* Set the range of VGA2 VGA2GAIN[4:0], not recommended to be used above 30dB */ - _vga2_range = osmosdr::gain_range_t( 0, 60, 3 ); + _vga2_range = osmosdr::gain_range_t( 0, 30, 3 ); /* Warn user about using an old FPGA version, as we no longer strip off the * markers that were pressent in the pre-v0.0.1 FPGA */ -- cgit v1.2.3
