The SHM-49 features excellent dynamic specifications including a maximum acquisition time of only 200 nanoseconds for a 10V step to ±0.01%. Sample-to-hold settling time, to ±0.01% accuracy, is 100 nanoseconds maximum with an aperture uncertainty of ±2 picoseconds. The SHM-49 is a complete sample/hold circuit, containing a preci- sion MOS hold capacitor and a MOSFET switching configuration which results in faster switching and better feedthrough attenuation. Addition- ally, a FET input amplifier design allows faster acquisition and settling times while maintaining a considerably lower droop rate.
