1D5 Option 1D5 improves the frequency reference accuracy.
The analyzer's synthesizer is phase locked to an oven
controlled crystal oscillator (OCXO), instead of the
standard VCXO. When present with narrow resolution
bandwidth (Option 1DR) it provides 1 Hz and 10 Hz
resolution bandwidths.
A4J Option A4J provides the analyzer with additional inputs
and outputs. They are as follows: SWP OUT, HI SWP
OUT (TTL), HI SWP IN (TTL), AUX VIDEO OUT, and
AUX IF OUT.
SWP OUT - sweep ramp output, provides a voltage ramp
proportional to the sweep of the analyzer (0 V to 10 V).
HI SWP OUT (TTL) - provides the HI SWP TTL signal
as an output (TTL high during a sweep, TTL low during
a retrace). It indicates when the analyzer is sweeping.
HI SWP IN (TTL) - allows external sweep control. It can
be grounded to stop sweeping.
AUX VIDEO OUT - provides detected video output
(before the analog-to-digital conversion) proportional to
vertical deflection of the trace.
AUX IF OUT - provides a 50 , 21.4 MHz IF output that
is the down-converted signal of the RF input of the
analyzer.
060 Option 060 provides reduced radiated and conducted
emissions to comply with EN55011 Class B
requirements. This option applies during ac operation
only.
Option 060 is incompatible with TV Trigger (Option
B7B).
UKB Option UKB extends the frequency range of the analyzer
on the low end to 100 Hz when DC coupling is selected.
This option requires installation of Option 1DR and is
only available on ESA models E4402B, E4404B, E4405B,
and E4407B.
