Version 2.5.2 of DoseMonitor, released at RSNA, adds a vast array of improved tools and analytics, including tracking of SAR (Specific Absorption Rate, SAR Max W/kg), slew rates
(dB/dt Max T/s), operating modes (normal, first level, etc.) and all other available MR parameters.
Conversely, electronic loads with a separate soft-start function and/ or programmable current slew rates
al low you to avoid abnormal operating conditions if the actual load has a soft-start capability.
Positive and negative slew rates
of the circuit are obtained as 223 V/[micro]s and 162 V/[micro]s, respectively.
System builders are able to define independent waveforms for each printhead, specifying the number of pulses and the slew rates
, amplitude and timings for each pulse.
Per Jedec specifications, the slew rates
of the signals determine how much more or less setup and hold time is required at the memory, on top of the base setup and hold requirements.
The PA78 Series in capable of achieving slew rates
of up to 350V/sec.
The novel input stage design Of this amplifier provides extremely high slew rates
in pulse applications while maintaining low quiescent current of under 1 mA, The output stages are well protected with user defined current limit although the safe operating area must be observed for reliable protection.
The new gradient packages, the Vantage MGV and the work-in-progress ZGV, feature gradient strengths of 30 mT/m and 33 mT/m (milliTesla per meter) and slew rates
of 86 mT/m/sec and 200 mT/m/sec (milliTesla per meter per second), respectively.
The EL5166 and EL5167 offer 6,000 volt-per-microsecond slew rates
while exhibiting low distortion of 1.7 nanovolts (nV) per root hertz.
When possible, the DUT designer should use logic families with the lowest possible output slew rates
and drive currents.
The current carrying capacity is 50 A, providing transients (slew rates
) as high as 400 A/[micro]s with a minimal required hoard area of only 11 in .
