Initial Accuracy: Better than ± 1 ppm at 20 o
C
Stability: Better than ± 1 ppm over 10 o
C to 30 o
C
Ageing: Better than ± 1 ppm per year

Resolution Bandwidth
RBW: Selectable between 10 MHz and 300 Hz
selectable in 1:3:10 sequence, or Auto
Video Filtering: Selectable between 10 MHz and 300 Hz
selectable in 1:3:10 sequence, or RBW Tracking
Markers
No. of Markers: One, Two (or None)
Resolution: 0.1 kHz at all frequencies
Marker Accuracy: 1/270th of Span ± 10Hz plus reference
frequency accuracy.
Readout: The frequencies at the marker points and
the frequency difference are displayed
Functions: Normal (Scroll Mode), Peak Find Mode,
Peak Track Mode, Frequency Measurement
Marker Frequency Counter
Frequency counted at the current active marker (M1 or M2) in
sweep or zero-span mode
Resolution: 10Hz, 100Hz or 1kHz
Accuracy: Reference frequency accuracy +/- 1 count
for signal > noise level +25dB
Channel Markers (only with Option U02)
Channel markers are a special case of Limit Patterns (see
Amplitude Limits within next section). Channel markers are
vertical lines at frequency points defined within a file. Most
commonly they will be used to mark channel centre frequencies
or channel boundaries.
No. of Points: Up to two files, each containing up to 49
points, can be displayed in differing colours.
Marker Files: Files are created using PSA-Manager
software. Up to 999 files can be stored.

over the the full operating frequency range
Linearity: Better than ± 1 dB over 60dB range down
from the reference level
Markers
No. of Markers: One, Two (or None)
Resolution: 0.1 dB
Readout: The level at the marker points and
difference are displayed.
