WARNING

Before applying power to this instrument, make sure it has been

properly grounded through the protective conductor of the ac power

cable to a socket outlet provided with protective earth contact. Any

interruption of the protective (grounding) conductor, inside or outside

the instrument, or disconnection of the protective earth terminal can

result in personal injury.

CAUTION

UTION

CA

Before applying p ower to this instrument, make sure its primary

power circuitry has b een adapted to the voltage of the ac power

source. Failure to set the ac power input to the correct voltage could

cause damage to the instrument when the ac power cable is plugged

in.

A carrier-to-noise measurement can be made very simply byusing

the delta-marker function. This can be demonstrated by using the

calibrator signal, placing a marker at the peak of the signal, then

placing a delta marker somewhere in the noise. The carrier-to-noise

measurement result is displayed in the active function area and is

Example 9. Format a

memory card and save

atrace

This task describ es how to format and save information on a memory

card. Information from the sp ectrum analyzer is sent via the MSIB

path to the HP 70004A's display where the memory card reader is

located.

1. Check that the memory card \write protect" switch is o.

This step is necessary to ensure that the memory card can be read

and written to by the card reader.

2. Place the memory card in the HP 70004A's memory-card reader.

To ensure that the memory card is selected as the mass storage

device, a memory card must rst be present in the card reader. If

a memory card is not inserted and the

This key sequence species that mass storage information for the

HP 70900B lo cal oscillator will be sent to the displayatHP-MSIB

the sp ectrum analyzer and the displayis now established so that

they communicate properly.

If the display address is

not

when you try to access the card reader. Note that the display

address is shown in the sp ectrum-analyzer display on the display

Example 10. Execute

the HP 70000 Customer

Demo Downloadable

Program (DLP)

Downloadable programs are programs resident in the spectrum

analyzer that are executable without an external computer. These

programs can b e either one-button solutions or interactive routines.

DLPs can b e accessed using the front-panel softkeys. They can also

be accessed via an external computer by sending the appropriate

programming commands allowing distributed processing.

A set of four example DLPs are downloaded into the HP 71209A

system before it is sent out from the factory. A package containing

these DLPs is included with your shipment if these DLPs are

missing. The HP 70000 Customer Demo DLP package contains: a

oppy disk with the four programs, an operation note with complete

DLP loading instructions, and the
