responding checkbox. Any or all of these features can be used at one time, however, the LFR
and Enhanced Throughput modes must be set up before the Resolution Enhancer is configured,
as discussed below.
Note that once an MCB is “trained” for the Resolution Enhancer (see the following section),
it must be “retrained” if any settings are changed that can affect peak shape or position (e.g.,
bias, gain, rise time, flattop, PZ).
Low Frequency Rejector — This feature is discussed in detail in Section 1.4.
!
The DSPEC Pro cannot optimize or pole-zero in LFR mode. Optimize or PZ with the
filter off, then turn it back on for data collection.
!
LFR mode affects the available range of protection times in Enhanced Throughput
Mode, as discussed in the next paragraph.
Enhanced Throughput Mode — See Section 1.2 for a discussion of this feature. The valid
Protection Time settings, in 25 ns increments, range as follows:
LFR Mode Highest Throughput
(minimum Protection Time)
Lowest Throughput
(maximum Protection Time)
Off (Rise Time + flattop) (2 × Rise Time + Flattop)
On (3 × Rise Time + 2 × Flattop) (6 × Rise Time + 3 × Flattop)
