About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
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. We have
made no changes to this manual copy. In other documentation, 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
HP8648A is now model number Agilent 8648A.

General Safety Considerations
WARNING
The instructions in this document are for use by qualified personnel only.To
avoid electrical shock, do not perform any servicing unless you are qualified
to do so.
The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the instrument from all voltage sources while it is being
opened.
The power cord is connected to internal capacitors that may remain livefor
five seconds after disconnecting the plug from its power supply.
This is a Safety Class 1 Product (provided with a protective earthing ground
incorporated in the power cord). The mains plug shall only be inserted in a
socket outlet provided with a protective earth contact. Any interruption of the
protective conductor inside or outside of the instrument is likelytomakethe
instrument dangerous. Intentional interruption is prohibited.
For continued protection against fire hazard, replace fuse only with same
type and ratings, (type nA/nV). The use of other fuses or materials is
prohibited.
W
ARNING
Before this instrument is switched on, mak
esure it has been properly
grounded through the protectiv
econductor of the ac po
w
er cable to asock
et
outlet pro
vided with protectiv
eearth contact.
Any interruption of the protectiv
e(grounding) conductor, inside or outside
the instrument, or disconnection of the protectiv
e earth terminal can result in
personal injury
.
Before this instrument is switched on, mak
esure its primary po
w
er circuitry
has been adapted to the v
oltage of the ac po
wer source.
F
ailure to set the ac po
w
er input to the correct voltage could cause damage
to the instrument when the ac power cable is plugged in.

General Information
The HP 70590A Options H69 and H72 TMAs (Test Mo dule Adapters) are MATE modules
for HP 70000 Series spectrum analyzers. The mo dules translate CI IL (control intermediate
interface language) into the HP 70000 Series native co de.
Option H69 mo dules provide a calibration switch signal at the rear panel. Option H72
mo dules switch the RF and Calibrator signals to the analyzer's RF input.
Note
There are no adjustment pro cedures for either the Option H69 or Option H72
Test Mo dule Adapters.

1-4 General Information

Input/Output Characteristics
Characteristics provide useful information by giving functional, but non-warranted,
performance parameters. The calibration switch will op erate upon issuance of the following
CIIL (control intermediate interface language) commands:
CNF
IST
CH 16 through 19
Discrete Fault Indicator (DFI)
The DFI is implemented as a normally closed relay whose coil is connected across the TMA's
power supply. The contacts open when power is applied. The contacts close when p ower is
removed from the system, the power supply shuts itself down, or the HP-MSIB lo op is broken.
