Signal Processing
Peak Hold
41
Note that other signal processing functions (like Averaging or Valley Hold) do not work
concurrently with Peak Hold.
7.2.3. Signal Slope (decay) in case of Peak Hold Reset
Three different signal drop (decay) functionalities are implemented and may be activated by
the PC based Multidrop Software, Ethernet or RS485 programming commands, or over the
rear control panel (Endurance user interface). Via the control panel is just an entry field given
to set the linear signal slope (decay).
7.2.3.1. Perpendicular signal drop (default mode)
The default mode (perpendicular signal drop) is activated, if both relevant signal decay values
(linear decay & averaging decay) are set to zero (0.0 Kelvin/second). This can be achieved via
the PC based Multidrop Software, Ethernet or RS485 programming commands, or over the rear
control panel (Endurance user interface).

7.2.3.2. Linear signal drop (decay mode)
The signal drop follows a linear decay function, where the decay value is given in Kelvin/second.
The linear decay value is settable via the PC based Multidrop Software, an Ethernet or RS485
programming command <XE>, or over the rear control panel (Endurance user interface).

7.2.3.3. Average time dependent signal drop (averaging mode)
The signal drop follows an averaging time function. The average time is the amount of time the
output signal needs to reach 90% magnitude compared to a perpendicular drop. This parameter
is set by means of the programming command <AA>.
