Hewlett-Packard to Agilent Technologies Transition
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and chemical analysis
businesses are now part of Agilent Technologies. To reduce potential confusion, the only
change to product numbers and names has been in the company name prefix: where a product
number/name was HP XXXX the current name/number is now Agilent XXXX. For example,
model number HP 8757D is now model number Agilent 8757D.

The HP 8757D Analyzer
The HP 8757D ( Figure 1-2
)isa micropro cessor-based receiv
er capable of making scalar
(magnitude only) reection and transmission measurements. The external detectors used
determine the frequency range. The raster displa
ypro
vides high resolution for viewing
measuremen
ts.
Note
The original HP 8757D incorp orated acatho de ra
ytube(CRT) based displa
y.
The curren
tdesign incorp orates a liquid crystal displa
y (LCD) based displa
y
.
In this man
ual, references to either CR
Tor LCD apply to both displa
ydesigns
unless noted otherwise.
CRT/LCD A
ttributes
The CR
T/LCD displa

of these attributes.
Displays
The analyzer can sim
ultaneously driv
eb
oth the internal display and one external monitor
(color or mono c
hrome, if compatible with the analyzer's scan rate and video lev

P
eripherals
Y
ou can use the analyzer to con

in
terface. Aprin
ter and plotter buer sp eeds measuremen

Calibration Data and Instrument States
Y
ou can store and recall instrumen
tstates and calibration data to and from external disks.
Measurement Channels
Four indep enden
t but identical measuremen
tc
hannels allowsim
ultaneous measuremen
ts and
viewing of measuremen
tparameters. The detector inputs (A, B, C, and R) accept A
CorDC
detected signals from detectors or bridges.
Local and Remote peration
You can op erate the analyzer either lo cally
, using the fron
t panel con
trols and men
u
selections, or remotely o
ver the HP-IB. Y
ou can also generate on-screen graphics (see \Remote
Operation").

our indep endent display channels pro cess signals from the HP 85025, 85026, 11664, or 85037 detectors and the
HP 85020 or 85027 ridges. The analyzer displays the data logarithmically
,in single input or ratio mode, with resp ect to
frequency
,on the in
ternal CR
T/LCD. Three detector inputs (A, B, and R) accept A
Cor
DC detected signals from detectors
or ridges.
Option 001 has four detector inputs (A, B, C, and R).
Modulator Driv
e
:The analyzer modulator driv eoutput provides the circuitry to driv
ethe HP 8340 and 8341 synthesized
sw
eep ers and the HP 11665B modulator. Y
ou can turn modulator drive on and o via either the frontpanel or HP-IB. In the
OFF state, the mo dulator drive signal turns the HP 11665B fully on for minim
um insertion loss. The 8360 and 8370
synthesized sw
eep ers ha
v
ethe capa ilit
yof modulating signals, so an external mo dulator such as the 11665B is not necessary
when using the 8360/8370 series.
