From de912a8df2f20b46ee0779d0ef4fad50f2c83679 Mon Sep 17 00:00:00 2001 From: Nick Foster Date: Thu, 26 May 2011 16:50:42 -0700 Subject: WBX: keep mixer on when TX idle, and switch TX ant sw to RX when idle to keep mixer from feeding out when idle. This allows USRPs to maintain a constant phase relationship between MIMO devices while operating. --- host/lib/usrp/dboard/db_wbx_common.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'host/lib/usrp/dboard/db_wbx_common.cpp') diff --git a/host/lib/usrp/dboard/db_wbx_common.cpp b/host/lib/usrp/dboard/db_wbx_common.cpp index 131729f42..f35677692 100644 --- a/host/lib/usrp/dboard/db_wbx_common.cpp +++ b/host/lib/usrp/dboard/db_wbx_common.cpp @@ -95,7 +95,7 @@ wbx_base::wbx_base(ctor_args_t args) : xcvr_dboard_base(args){ this->get_iface()->set_gpio_ddr(dboard_iface::UNIT_RX, RX_PUP_5V|RX_PUP_3V|ADF4350_CE|RXBB_PDB|ADF4350_PDBRF|RX_ATTN_MASK); //setup ATR for the mixer enables - this->get_iface()->set_atr_reg(dboard_iface::UNIT_TX, dboard_iface::ATR_REG_IDLE, TX_MIXER_DIS, TX_MIXER_DIS | TX_MIXER_ENB); + this->get_iface()->set_atr_reg(dboard_iface::UNIT_TX, dboard_iface::ATR_REG_IDLE, TX_MIXER_ENB, TX_MIXER_DIS | TX_MIXER_ENB); this->get_iface()->set_atr_reg(dboard_iface::UNIT_TX, dboard_iface::ATR_REG_RX_ONLY, TX_MIXER_DIS, TX_MIXER_DIS | TX_MIXER_ENB); this->get_iface()->set_atr_reg(dboard_iface::UNIT_TX, dboard_iface::ATR_REG_TX_ONLY, TX_MIXER_ENB, TX_MIXER_DIS | TX_MIXER_ENB); this->get_iface()->set_atr_reg(dboard_iface::UNIT_TX, dboard_iface::ATR_REG_FULL_DUPLEX, TX_MIXER_ENB, TX_MIXER_DIS | TX_MIXER_ENB); -- cgit v1.2.3
