BIRD IQC5000B - Acquisition Bandwidth

Operating Instructions
30
Following is a brief description of the possible record start/stop methods:
 Immediate (Manual) (start and/or stop) – starts/stops a recording immediately on user input.
 Time of day (start and/or stop) – starts/stops a recording at a specified time of day.
 Trigger (start and/or stop) – starts/stops a recording based on trigger parameters.
o 2 TTL-level trigger inputs
o R
ising or Falling edge
 Duration (stop only) – records for a specified duration of time or samples
Acquisition Bandwidth
The Acquisition Bandwidth, Recording Bandwidth, or Recording Span all refer to the instantaneous bandwidth that
will be recorded. With a center frequency at 400 MHz, a 10 MHz acquisition bandwidth would record all signals ± 5
MHz from 400 MHz (395 to 405 MHz).
Keysight and Rohde & Schwarz recor

re capable of arbitrary acquisition bandwidths below their max
supported span, down to 19.531kHz. Tektronix RSA and Anritsu Field Master Pro recordings are set to discrete
acquisition bandwidths according to set sample rates.
