Ancillary Measurements Period, Pulse width
Time stamping
Capable of providing raw time stamp data together with pulse counts on inputs. Accessible over
programmatic interfaces only. Timestamping is not available for MCA3000 Series channel C.
Time-Stamp-capable
channels
FCA3000 Series: A, B, C
FCA3100, MCA3000 Series: A, B
Maximum Sample Speed See GPIB specifications.
I/O Transfer Rate determines Maximum Sample Speed.
Maximum Frequency 160 MHz
Maximum Frequency to catch
each edge
250 kHz (FCA3000, FCA3100 S eries)
Minimum Pulse Width
2.5 ns (FCA3000, FCA3100 Series)
Timestamp Resolution
70 ps (FCA3000 Series)
50 ps (FCA3100 Series)
Voltage Measurement,
Channels A and B
Capable of identifying positive peak and negative peak voltages
Vmax = Signal (positive peak) + Noise (pk) – 1/2 hysteresis
Vmin = Signal (negative peak) – Noise (pk) + 1/2 hysteresis
Range 1X attenuator: –5 V to +5 V
10X attenuator: –50 V to +50 V
Frequency Range

is calculated from the Vmax and Vmin values. Thus it has twice the error band.
Resolution (FCA3000 Series)
1X attenuator: 3 mV
10X attenuator: 30 mV
