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> 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.
*ESESets 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

Arguments <NR1> specifies 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.
