4 Service Connector. The service connector is for
service use only.
5 Inputs/Outputs (Refer to Agilent Technologies ESA
Spectrum Analyzer Specifications Guide for more

5a VGA OUTPUT drives an external VGA
compatible monitor with a signal that
has 31.5 kHz horizontal, 60 Hz vertical
synchronizing rate, non-interlaced.
5b GATE/HI SWP OUT (TTL) is high when
the analyzer is sweeping or when
Gate
(Option 1D6) is active.
5c GATE TRIG/EXT TRIG IN (TTL) accepts the
positive edge of an external voltage
input that triggers the analyzer
internal sweep source or the gate
function (Time Gate, Option 1D6).
Table 2-1 and Table 2-2 show the appropriate rear panel slots to be used
