Installation
Safety
Considerations
There are no hazardous v
oltages in this detector.
Initial Inspection
1. Chec
the shipping con
tainer and pac
aging material for damage.
2. Chec
that the shipmen
tis complete.
3. Chec
connector, cable, and detector body for mec
hanical damage.
4. Chec
the detector electrically:
Either ma
eameasuremen
tor test to specications. (See Chapter
3, \Operation" or Chapter 4, \P
erformance T
ests.")
If an
yof the follo
wing conditions exist, notify y
our nearest Agilen
t
oce:
incomplete shipmen
t
mec
hanical damage or defect
failed electrical test
If y
ou nd damage or signs of stress to the shipping con
tainer or the
cushioning material,
eep them for the carrier's insp ection. Agilen
t
does not w
ait for aclaim settlemen
tbefore arranging for repair or
replacement.
Installation -1

Preparation for Use
Caution
Do not sub ject the detector to mec
hanical sho c
.
Electrostatic Discharge
(E D)
ESD can damage the highly sensitiv
emicro circuits in this device;
c
harges as lo
was 100 V can destro
ya detector.
ESD damage occurs most often as you connect or disconnect a
device. Use this detector at astatic-safe w
or station and w
ear a
grounding strap.
Never
touc
hthe input connector cen
ter contacts or
the cable con
tact pins.

Static-Safe
Practices
Before cleaning, inspecting, or ma ing a connection to a
static-sensitive device or test port, ground y
ourself as far as
possible from the test p ort.
Discharge static electricity from a device b efore connecting it:
Touch the device briey (through a resistor of at least 2 M) to
either the outer shell of the test p ort, or another exp osed ground.
This discharges static electricity and protects test equipment
circuitry.

Mating a Precision 3.5 mm Connector to an SMA Connector
It is possible to mate a precision 3.5 mm connector to an SMA
connector, but this is not ideal because the t
w
o connectors hav
e
slightly dierent dimensions and mechanical characteristics. Mating
aprecision 3.5 mm connector to an SMA connector also aects the
electrical performance. (See \Electrical P
erformance".) Use the
following pro cedure to safely mate 3.5 mm and SMA connectors.
1. Insp ect the SMA connector.
Nev
er mate aprecision 3.5 mm connector to an SMA connector
in whic
hthe solid plastic dielectric protrudes in fron
tof the outer
conductor mating plane.
2. Gage both connectors. The SMA connector m
ust meet the
precision 3.5 mm connector setbac
specications. If not, it will
damage the 3.5 mm connector.
In some SMA connectors, the male con
tact pins are not held
securely and are easily pulled out of specication (esp ecially if
the female connector contact ngers are tigh
t). Also, some SMA
male pins are not true pins, but are the cut-o ends of the cen
ter
conductor in semi-rigid coaxial cable. In this case, misalignmen
t
and burrs are li
ely to occur.
3. Carefully align the connectors.
4. Push the t
w
oconnectors together with the male con
tact pin
precisely concen
tric with the female.
5. Do not t
wist either connector or device.
6. T
urn only the outer male connector n
ut.
7. Use a60 N-cm (5 in-lb) torque wrenc
hfor the nal connection.
If y
ou m
ust ma
emore than a few connections, use a
3.5 mm-to-3.5 mm adapter to protect the 3.5 mm connector.
Electrical P
erformance.
The electrical performance of the junction of
t
wo precision 3.5 mm connectors is superior to the junction of either
t
w
oSMA connectors, or an SMA connector mated to aprecision
3.5 mm connector. (See Figure 2-3
.)
When y
ou mate an SMA connector with a precision 3.5 mm
connector, the connection has a t
ypical mismatc
h (SWR) of
1.10 at 2 GHz. This mismatch is less than that of t
w
o SMA
connectors, but is m
uch higher than that of t
wo precision 3.5 mm
connectors.
