TRIGger:A:BA
NDWidth:RF:LOW? (Query Only)
Returns the low end of the power level trigger bandwidth range as an NR3 value
in hertz. This is the value that is displayed in the user interface when the trigger
source is RF.
This command requires the MDO4TRIG advanced trigger feature to be enabled.
Conditions
MDO4000/B and MDO4000C with option SA3 or SA6 only.

TRIGger:A:BANDWidth:RF:LOW?
TRIGge
r:A:BUS
This command specifies the bus type to trigger on. It supports CAN, I
2
C, SPI,
RS-232, Ethernet, MIL-STD-1553, LIN, USB, audio, FlexRay buses (with the
appro
priate application module installed) as well as parallel signals (MDO4000/B
and MDO3000 and MDO4000C series with option MDO3MSO or MDO4MSO
only.). There are up to four buses, B1–B4; three buses, B1 – B3 for the
MDO4000C models; two buses for MDO3000, which only has two buses, B1–B2.
Each bus can be independently set to one of the serial trigger types.

C or SPI bu
s signals, install the DPO4EMBD application module,
except for MDO3000 models, which require MDO3EMBD.
For RS-232, RS
-422, RS-485, or UART bus signals, install the DPO4COMP
module, except for MDO3000 models, which require MDO3COMP.
For I

S, Lef
t Justified (LJ), Right Justified (RJ), or TDM bus signals, install
the DPO4AUDIO module, except for MDO3000 models, which require
MDO3AUDIO.
For CAN or LIN bus signals, install the DPO4AUTO or DPO4AUTOMAX
module, except for MDO3000 models, which require MDO3AUTO.
For FlexRay bus signals, install the DPO4AUTOMAX module, except for
MDO3000 models, which require MDO3FLEX.
For Ethernet signals on the MDO4000/B/C and MSO4000B and DPO4000B,
install the DPO4ENET module. Note that ≥350 MHz bandwidth models
are recommended for 100BASE-TX.
For MIL-STD-1553 bus signals, install the DPO4AERO module, except for
MDO3000 models, which require MDO3AERO.
For USB bus signals, install the DPO4USB module, except for
MDO3000 models, which require MDO3USB. Note that 1 GHz bandwidth
models are recommended for high-speed (HS) USB.
A table is available listing the commands enabled by each application module.
