Commands Listed in Alphabetical Order
Arguments
<NR3> isafloati
ng point number that specifies the position of the digital channel,
in slot units. Use the oscilloscope front-panel controls to place the channel; then
query the channel to obtain an exact value for the position.
D<x>:THResh
old
This command specifies the logical threshold for the digital channel <x>, where x
is the digital channel number D0 – D15.
NOTE. MDO3
000 models only have two digital threshold controls: one for digital
channels D0 - D7, and the other for D8 - D15. Changing one digital channel’s
threshold l evel changes all of the channels’ levels in the same set.
Conditions
Requires an MSO or MDO4000/B/C model, or MDO3000 with option
MDO3MSO installed.

Syntax
D<x>:THReshold {ECL|TTL|<NR3>}
D<x>:THReshold?
Arguments
ECL sets the digital threshold for channel <x> to a preset ECL high level of -1.3V.
TTL sets the digital threshold for channel <x> to a preset TTL high level of 1.4V.
<NR3> is a floating point number that specifies the digital threshold for channel
<x>, in volts.
Examples
D5:THRESHOLD ECL sets the threshold for D5 digital channel to ECL levels.
D14:threshold? might return :D14:THRESHOLD 1.2500 indicating that the
threshold level for the D14 digital channel is 1.25 volts.
*ESE
Sets and queries the bits in the Event Status Enable Register (ESER). The
ESER prevents events from being reported to the Status Byte Register (STB).
For a detailed discussion on how to use registers, see Registers. (See page 3-1,
Registers.)

Syntax
*ESE <N R1>
*ESE?
Related Commands
*CLS, DESE, *ESR?, EVENT?, EVMsg?, *SRE, *STB?
Arguments
<NR1> speci
fies the binary bits of the ESER according to this value, which ranges
from 0 through 255.
The power-
on default for the ESER is 0 if *PSC is 1. If *PSC is 0, the ESER
maintains the previous power cycle value through the current power cycle.
NOTE. Setting the DESER and the ESER to the same values allows only those
codes to be entered into the Event Queue and summarized on the ESB bit (bit 5) of
the Status Byte Register. Use the DESE command to set the DESER.
Exampl
es
*ESE 209 sets the ESER to binary 11010001, which enables the PON, URQ,
EXE, and OPC bits.
*ESE? might return 186, showing that the ESER contains the binary value
10111010.
*ESR? (Query Only)
Ret
urns the contents of the Standard Event Status Register (SESR). *ESR? also
clears the SESR (reading the SESR clears it). For a detailed discussion on how to
use registers, see Registers. (See page 3-1, Registers.)
