General Information
Table 1-1. Model8565A Specifications (2 of 3)
Average noise level:
Sensitivity (minimum discernible signal) is given by the signal
level which is equal to the average noise level, causing approx-
imately a 3 dB peak above the noise. Maximum average noise
level with 1 kHz Resolution Bandwidth (0 dB attenuation and
0.003 (3 Hz) video filter) is given in the table below:

Reference Level
Reference Level range:

steps and continuous 0 to -12 dB calibrated vernier.
Reference Level accuracy:
With Sweep Time/Division control in Auto setting, the opti-
mum sweep rate is selected automatically for any combin-
ation of Frequency Span/Div, Resolution Bandwidth and
Video Filter settings. Thus, the Auto Sweep setting insures
a calibrated amplitude display within the following limits:

Calibrated display range
Log -expanded from reference level down:
70 dB with 10 dB/Div scale factor
40 dB with 5 dB/Div scale factor
16 dB with 2 dB/Div scale factor
8 dB with 1 dB/Div scale factor
Linear. Full scale from 56 p.V ( -102 dBm across 50 ohms
to 707 volts (+70 dBm)1 in 10 dB steps and continuous 0 to
-12 dB vernier. Full scale signals in linear translate to ap-
proximately full scale signals in the log modes.
Display accuracy
Log:
<
±0.1 dB/dB but not more than ±1.5 dB over full
70 dB display range.
Linear:
<

Residual responses (no signal present at input):
With 0 dB input attenuation on fundamental mixing (0.01 to
4.1 GHz)
<

Signal Identifier: Provided on all Frequency Bands in
1 MHz/Div frequency span for signal identification (reads
incorrectly for 100 MHz Cal Output signal)
SWEEP SPECIFICATIONS
SWEEP TIME
Auto: Sweep time is automatically controlled by Frequency
Span/Div, Resolution Bandwidth and Video Filter controls to
maintain an absolute amplitude calibrated display.
Calibrated Sweep times: 21 internal sweep times from 2
p.sec/Div to 10 sec/Div in 1, 2, 5, 10 sequence. Sweep time
accuracy ±10% except for 2, 5, and 10 sec/Div which are
± 20%. Swept frequency modes use sweep times 2 msec/Div
through 10 sec/Div. When operated as a fixed tuned receiver
(Zero Span) the full range of sweep times(2 p.sec to 10 sec/
Div) may be used to display modulation waveforms.
