Waveform Notes:
1. Minimum realizable duty cycle is limited by current range response and load
impedance.
2. Amplitude accuracy is applicable for 100mA through 2
μ
A ranges (Fast
Mode) into a maximum resistive load of 2V/I
fullscale of range
. Amplitude
attenuation will occur at higher frequencies dependent upon current range and
load impedance.
3. For frequencies less than 1 Hz, duty cycle not tested, guaranteed by design.
4. These Specifications are only valid for the 20mA range and a 50

load.
5. These characteristics for informational purposes only.
6. Typical values are non-warranted, apply at 23
