Dynamic Range
The N2820A and N2821A probes provide a large dynamic
measurement range (>20,000:1 or 86 dB on the zoomed-in
channel) that allows you to observe both the entire current
waveform and extremely small current fluctuations. As shown in
, you could simultaneously view a mobile phone’s 135 mA
receive current pulses and 2 mA idle current in the presence of 2A
transmit current pulses, with a single acquisition. When using
N2820A probes on Infiniium oscilloscopes, use the powerful new
dual-grid view as explained in
Zoomed-In/Zoomed-Out Waveforms”

R
SENSE
Value and Dynamic
Range
Since the N2820A probe has two outputs, each with a different
gain, dynamic range encompasses both channels while using a
single
R
SENSE
value. For example, with a 100 m
Ω
R
SENSE
resistor, the
zoomed-in waveform can display about 50 µA and the zoomed-out
channel can display about 2.2A for a dynamic range of
approximately 93 dB:
