Notes

WARNING

CA

UTION

This instrument has been designed and tested in accordance with

IEC Publication 348, Safety Requirements for Electronic Measuring

Apparatus, and has been supplied in a safe condition. The instruction

documentation contains information and warnings which must be

followed by the user to ensure safe operation and to maintain the

instrument in a safe condition.

The

following

safety

notes

are

used

throughout

this manual.

Familiarize yourself with each of the notes and its meaning before

operating this instrument.

Warning denotes a hazard. It calls attention to a procedure

which, if not correctly performed or adhered to, could result in

injury or loss of life.Do

not

proceed beyond a warning note until

the indicated conditions are fully understood and met.

Caution

denotes

a

hazard.

General Safety Considerations

WARNING

CAUTION

No operator serviceable parts inside. Refer servicing to

qualied personnel. To prevent electrical shock, do not remove

covers.

If this instrument is not used as specied, the protection

provided by the equipment may be impaired. This instrument

must be used in a normal condition (in which all means for

protection are intact) only.

For continued protection against re hazard, replace line fuse

only with same type and rating ([F 5A/250V]). The use of other

fuses or material is prohibited.

Before switching on this instrument, make sure that the line voltage

selector

switch

is set to the voltage of the power supply and the

correct fuse is installed.

Always use the three-prong ac power cord supplied with this

instrument. Failure to ensure adequate earth grounding by not

using this cord may cause instrument damage.

Preparing for Use

Introducing the EMI Receiver

The EMI receiver includes the receiver RF section, the RF lter

section, and all the accessories you will need to prepare the system

for use.

This chapter contains information about accessories supplied, initial

inspection, electrostatic discharge, and available power cables.

In addition, installation procedures show how to install the handles,

lock the system together, set the line voltage selector switches, check

the fuses, add the front and rear cables, and set the HP-IB address.

Hewlett-Packard oce. If the shipping container is damaged or the

cushioning material shows signs of stress, also notify the carrier. Keep

the shipping materials for the carrier's inspection. The HP oce

will arrange for repair or replacement without waiting for a claim

settlement.

If the shipping materials are in good condition, retain them for

possible future use.You may wish to ship the EMI receiver to another

location or return it to Hewlett-Packard for service. See \Returning

All work on electronic assemblies should be performed

(ESD) can damage or destroy electronic

static-safe work station using two types of ESD protection:

Conductive table-mat and wrist-strap combination.

Conductive oor-mat and heel-strap combination.

Both types, when used together, provide a signicant level of

ESD protection. Of the two, only the table-mat and wrist-strap

combination provides adequate ESD protection when used alone.

To ensure user safety, the static-safe accessories must provide at least

1 M of isolation from ground. Refer to Table 1-2 for information on

ordering static-safe accessories.

Do not use either of the two types of ESD protection described

above for a static-safe work station when working on circuitry

Operation Verication

This chapter contains operation verication test procedures that test

the electrical performance of the receiver.

Allow the receiver to warm up in accordance with the Temperature

Stability specication before performing the tests in this chapter.

None of the test procedures involve removing the cover of the

receiver.

Operation verication tests only the most critical specications of

the receiver. These tests are recommended for incoming inspection,

troubleshooting, or after repair.

Before You Start

There are four things you should do before starting an operation

verication test:

Switch the receiver on and let it warm up in accordance with the

Temperature Stability specication in Chapter 2.

Read \Making a Measurement" in Chapter 2 of the User's Guide.

After the receiver has warmed up as specied, perform the

self-calibration routines as follows:

Read the rest of this section before you start any of the tests, and

make a copy of the Operation Verication Test Record at the end of

this chapter.

Test equipment you will need

Tables 2-2 through 2-4 list the recommended test equipment,

accessories, and cables for the manual operation verication. Any

equipment that meets the critical specications given in the table can

be substituted for the recommended model.

Recording the test results

A operation verication test record is provided at the end of this

chapter.

Each test result is identied as a

verication tests and on the operation verication test record. We

recommend that you make a copy of the operation verication test

record, record the test results on the copy, and keep the copy for your

test record. This record could prove valuable in tracking gradual

changes in test results over long periods of time.

of a020 dBm signal and this becomes the reference

signal level. The attenuator is set to the 0 dB setting and the signal is

measured. The input attenuator accuracy is obtained by subtracting

the reference signal from this reading. The attenuation is then set

to the 20 dB step and another reading of the signal is made. Again

the reference signal is subtracted from the reading. The procedure is

tested

signal and the attenuator is set to the 10 dB setting. The receiver

reads the power level and this becomes the reference signal level.

The attenuator is set to the 0 dB setting and the signal is measured.

Input attenuator accuracy is obtained by subtracting the reference

signal from this reading. The attenuator is then set to the 20 dB step.

Another reading of the signal is made. Again the reference signal is

subtracted from the reading. The measurement is repeated for the 30,

40, 50, 60 and 70 dB attenuator steps. This procedure is repeated for

both frequencies and then at 50 MHz for INPUT 2.

7. EMI Receiver Reference Level Accuracy

A

50

MHz CW signal is applied to INPUT 2 of the EMI receiver

through

amplitude

two

step attenuators. The attenuators increase the eective

range

of the source. The amplitude of the source is

decreased in 10 dB steps and the receiver marker functions are used

to measure the amplitude dierence between steps. The source

internal attenuator is used as the reference standard. The test is

performed in both log and linear amplitude scales.

It is only necessary to test reference levels as low as090 dBm (with

10 dB attenuation) since lower reference levels are a function of the

receiver microprocessor manipulating the trace data. There is no error

associated with the trace data manipulation.

two step attenuators. The attenuators increase the

range of the source. The amplitude of the source

is decreased in 10 dB steps and the receiver marker functions are

used to measure the amplitude dierence between steps. The source

internal attenuator is used as the reference standard. The test is

performed in both log and linear amplitude scales.

It is only necessary to test reference levels as low as090 dBm (with

10 dB attenuation) since lower reference levels are a function of the

receiver microprocessor manipulating the trace data. There is no error

associated with the trace data manipulation.
