Measurement accuracy
High repeatability and features such
as tunable marker with frequency
count allow measurements to be made
more accurately and conveniently
than ever before.
Less than 1 x lO
–9
/day frequency
error, together with spectrum
analyzer selectivity, make counter
frequency accuracy possible even
when measuring small signals in the
presence of large ones. An internal
error correction routine reduces the
amplitude measurement uncertainty
due to changes in various analyzer
controls.
Under automatic control, the
analyzer's exceptional repeatability
may be used to further characterize
sources of measurement uncertainty,
and thereby enhance accuracy.
Amplitude measurement range
The amplitude measurement range
extends from +30 dBm to –135 dBm
with 90 dB calibrated display,
and the input is protected from
accidental overload. Calibration
units can be selected from dBm,
dBmV, dBµV, and volts. The analyzer
measures signal levels as low as
32 nV (across 50 ohms).
Frequency measurement range
The frequency measurement range
extends from 100 Hz to 1500 MHz
with dc and ac coupled inputs. The
analyzer's measurement capability
extends from RF down to audio
frequencies
Outstanding performance
A sophisticated phase lock system combines “synthesizer-like” tuning and
frequency accuracy with superior local oscillator spectral purity to make
narrow resolution bandwidths practical at RF frequencies and virtually
eliminate long-term drift. This system is administered by an internal
microcomputer which also makes possible powerful operational features
described in later pages.
