Configuration
Pulse length:
This value describes the time for pulses. Default: 100 us
Dead time:
The dead time is the waiting time after the pulse before sampling begins. Default: 20 us
Recycle delay:
This value represents the repetition rate for the pulse programmer. Default: 1ms (i.e. 1
kHz repetition)
Number of points:
The number of data points averaged by the FPGA within the recycle delay. The maxi-
mum value is (recycle delay - pulse length - dead time) / 12.5 MHz. Default: 4000
points.
NMR frequency:
This is the 2H NMR frequency including chemical shift offset. There is no default as this
value is set by EDLOCK.
Gain:
This is the gain for the receiver path. 40 dB means no gain in relation to the pre-ampli-
fier. The range is from 40dB to 106 dB. Note that this is NOT the gain set by the lock dis-
play panel which is a pure digital display factor. The hardware gain remains constant and
