BUS:B<x>:PAR
allel:CLOCk:SOUrce
Specifies the clock source waveform for the parallel bus.
Conditions
Requires an MSO/MDO model, with the MDO3MSO option installed for the
MDO3000 series. The MSO4000B and MDO4000/B/C models can trigger on
parallel buses without an application module.

D0|D1|D2|D3|D4|D5|D6|D7|D8|D9|D10|D11|D12|D13|D14|D15}
BUS:B<x>:PARallel:CLOCk:SOUrce?
Arguments
CH1–CH4 specifies an analog channel to use the clock source waveform.
D0-D15 specifies a digital channelas the clock source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
BUS:B<x>:PARallel:WIDth
This command specifies the number of bits to use for the width of the parallel bus.
Conditions
Requires an MSO/MDO model, with the MDO3MSO option installed for the
MDO3000 series. The MSO4000B and MDO4000/B/C models can trigger on
parallel buses without an application module.

BUS:B<x>:POSition <NR3>
BUS:B<x>:POSition?
Argume
nts
<NR3> is a floating point number that specifies the position of the bus <x>
waveform on the display.
BUS:B<x>:RS232C:BITRate
This
command specifies the bit rate for the RS-232 bus.

Syntax
BUS:B<x>:RS232C:BITRate <NR1>
BUS:B<x>:RS232C:BITRate?
Arguments
<NR1> is the bit rate in bits-per-second. You can enter any positive integer, and
the instrument will coerce the value to the closest supported bit rate.
BUS:B<x>:RS232C:DATABits
This command specifies the number of bits in the data frame for the RS-232 bus.
Conditions
This command requires a DPO4COMP application module for 4000 series
models, and an MDO3COMP application module for MDO3000 series models.
Group

Syntax
BUS:B<x>:RS232C:DATABits {7|8|9}
BUS:B<x>:RS232C:DATABits?
Arguments
7 specifies seven bits in the RS-232 data frame.
8 specifies eight bits in the RS-232 data frame.

32C:DELIMiter
This command specifies the delimiting value for a packet on the RS-232 bus.
Conditions
This command requires a DPO4COMP application module for 4000 series
models, and an MDO3COMP application module for MDO3000 series models.

BUS:B<x>:RS232C:DELIMiter?
Arguments
NULl specifies 0x00.
LF specifies 0x0A.
CR specifies 0x0D.
XFF specifies 0xFF.
BUS:B<x>:RS232C:DISplaymode
This command specifies the display mode for the RS-232 bus (frame or packet).
Conditions
This command requires a DPO4COMP application module for 4000 series
models, and an MDO3COMP application module for MDO3000 series models.

Syntax
BUS:B<x>:RS232C:DISplaymode {FRAme|PACKET}
BUS:B<x>:RS232C:DISplaymode?
Arguments
FRAme displays each frame as a single entity.
PACKET displays a group of frames terminated with a single frame defined by the
BUS:B<x>:RS232C:DELImiter command or the front panel.
BUS:B<x>:RS232C:PARity
This command specifies the parity for the RS-232C bus.
