From 03b493c129f06147a6e59ecbade9fa02fc468b06 Mon Sep 17 00:00:00 2001 From: Martin Braun Date: Wed, 11 May 2022 16:04:31 +0200 Subject: n320: Improve comments regarding low band The N320 code include some constants that were either unused or incorrect. This clarifies the lowband frequency. --- host/lib/usrp/dboard/rhodium/rhodium_bands.cpp | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'host/lib/usrp/dboard/rhodium/rhodium_bands.cpp') diff --git a/host/lib/usrp/dboard/rhodium/rhodium_bands.cpp b/host/lib/usrp/dboard/rhodium/rhodium_bands.cpp index 6c16a7d7f..8a41b4b2b 100644 --- a/host/lib/usrp/dboard/rhodium/rhodium_bands.cpp +++ b/host/lib/usrp/dboard/rhodium/rhodium_bands.cpp @@ -20,6 +20,9 @@ namespace { * The RX path has 8 bands, which we call BAND0 through BAND7.
