External Mixing AYZ Option AYZ allows the use of HP/Agilent 11970 Series,
and HP/Agilent 11974 external mixers with the Agilent
E4407B analyzer to extend the frequency range to 110
GHz. Operation to 325 GHz is also possible with
non-HP/Agilent mixers.
Fast Digitized Time
Domain Sweeps
AYX Option AYX allows fast digitized sweep times as fast as
20
µsec in spans of 0 Hz. Refer to the Sweep key
description in your User’s guide for information about
possible sweep times. It also provides the following
additional inputs and outputs:
Option AYX - 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 and reset the sweep.
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
Ω, 21.4 MHz IF output
that is the down-converted signal of the RF input of
the analyzer.
For A.07.00 firmware revisions and later, either this
option or Option B7D (Digital Signal Processing and
Fast ADC) is required to perform the PowerStat
Complementary Cumulative Distribution Function
(PowerStat CCDF) for all radio standards. It is also
required to perform the ACP measurement when the
NADC radio standard is selected.
Firmware Upgrade Kit UE2 Option UE2 provides the most current ESA spectrum
analyzer firmware on 3-1/2 inch floppy disks.
