Table A–2: Frequency-Related Characteristics (Cont.)
Characteristic Supplemental Information Performance Requirement
Resolution Bandwidth (6 dB down) Resolution bandwidth selections are:
5 MHz, 1 MHz, 300 kHz, 100 kHz,
30 kHz, 10 kHz, 3 kHz, 1 kHz, and
300 Hz for the spectrum analyzer
Shape Factor (60 dB/6 dB) 7:1 or less for all resolution bandwidths
≤
1 MHz
Noise Sidebands
≤
–70 dBc at 30X Resolution Bandwidth
for all resolution bandwidths
≤
100 kHz
Video Filter Reduces video bandwidth to about 1% of
the selected resolution bandwidth; or one
of 12 video filters (3 Hz, 10 Hz, 30 Hz,
100 Hz, 300 Hz, 1 kHz, 3 kHz, 10 kHz,
30 kHz, 100 kHz, 300 kHz, or WIDE) can
be selected from the UTIL menu
Table A–3: Frequency/Amplitude Related Characteristics
Characteristic Performance Requirement Supplemental Information
Marker The frequency and amplitude values of
the marker position are displayed and
are preceded by the letter M
[MKR] [
'
] and [MKR] [
a
] position the
marker to the next right or left signal
peak, respectively
Accuracy
Frequency Same as SPAN/DIV
Amplitude A function of the reference level, vertical
scale factor, and normalizations (see
Display Dynamic Range on page A–15)
Also, flatness corrections while in CATV
mode for range of 15 MHz to 1.105 GHz
Delta Marker When activated, a second marker is
displayed at the same frequency as the
first marker. This is the “Reference
Marker” The FREQ/MARKERS control may be
used to position the first marker; the
frequency and amplitude differences
between markers are readouts preceded
by the letter D
Accuracy
Frequency 1 PPM
±
10 Hz of the higher marker
frequency
With both signals counted
Amplitude Same as Marker
