Summary

Introduction

The TeMronix 2707 External Tracking Generator

is

a powerful tool for rneasuring the frequency response of a variety of active and passive devices. You can use the External Tracking Generator to determine the frequency response of the following:

filters

H

crystals

amplifiers cables

w

most other two-port devices

The standard External Tracking Generator has a 50 R output

and

is controlled by either the TeMronix 271 1 or 2712 Spectrum Analyzer. The External Tracking Generator with Option 01 has a

75

R

output and is controlled with

a TeMronix

271

4

Spectrum Analyzer.

The

External Tracking Generator produces an

RF

sine wave signal whose output frequency tracks the frequency being analyzed by the controlling spectrum analyzer. For example, if the spectrum analyzer is sweeping from

55

MHz

to

300

MHz, the output frequency of the External Tracking Generator

sweeps synchronously from

55

MHz to 300 MHz. You can compensate for circuit drift or propagation delays through the device under test by offsetting the External Tracking Generator slightly (typically

-5

kHz

to $60

kHz)

with

respect to the spectrum analyzer frequency.

You can vary the output level of the standard External Tracking Generator from

-48

dBm to

0

dBm

(or the equivalent in other reference level units available on the spectrum analyzer). You can vary the output level of the External Tracking Generator with Option 01 from -1.2

dBmV

(-50

dBm)

to

46.8

dBmV (-2 dBm). You can also use the front-panel

LEVEL

control on

the spectrum analyzer to vary the External Tracking Generator output level.

how to mechanically attach your

2707

External Tracking Generator to its

controlling spectrum analyzer how to electrically connect the External Tracking Generator to the con-

trolling spectrum analyzer

how to use the External Tracking Generator to perform a useful task

a simple procedure that allows you to quickly check the functional operation of the External Tracking Generator

Mechanical Connections

You can mechanically attach the External Tracking Generator to its control-

ling spectrum analyzer using the standard accessories provided with your External Tracking Generator. Refer to Figure

1-1

when performing the follow-

ing steps.

Preparing the Spectrum Analyzer

1.

Turn the spectrum analyzer bottom side up.

2.

Slide the four stud plates into their mounting slots on the cabinet of the

spectrum analyzer.

3.

Install an

8-32

nut on each of the threaded studs. The nuts are used as spacers to provide clearance for the front cover of the spectrum analyzer.

4.

Position the mounting plate so that the cutouts for the feet and the holes

for the threaded studs align properly.

5.

Secure the mounting plate to the studs with four.

832

nuts and four flat

washers.

Preparing the External Tracking Generator

1.

The trim strips along the upper sides of the External Tracking Generator are attached with

Velcro@. Use a small, flat-blade screwdriver to carefully

lift the trim strips

at

the front or rear of the cabinet (whichever end has the widest gap between the trim and the cabinet). Pull the trim strips out and remove them.

Normalizing the External Tracking Generator

The External Tracking Generator is normalized by determining the VCO voltage needed to center its output signal in the narrowest resolution bandwidth filter at 100 MHz. Its output amplitude at 100 MHz is then measured by the spectrum analyzer and properly adjusted as it is stepped through its entire range.

3-5

Operation

To ensure maximum accuracy when making External Tracking Generator

measurements, the External Tracking Generator must first be normalized.

Because External Tracking Generator normalizations depend on the spectrum analyzer reference, the instrument normalizations must be valid to achieve optimum results. Refer to your spectrum analyzer user manual for information about normalizing the spectrum analyzer.

To normalize the External Tracking Generator, ensure the instrument has warmed up for at least

15

minutes and is in spectral display mode.

t

3-6

Operation

External Tracking Generator normalization is not continuously monitored by

the spectrum

analyzer. To avoid inaccuracies due to temperature differences, long-term drift, or other causes, we recommend that you periodically normalize the External Tracking Generator during long measurement sessions, or readjust the tracking to keep narrow resolution bandwidth filters properly aligned.

In some spectrum analyzers, the peak of the 5 MHz resolution bandwidth

filter does not occur precisely at the center of its bandpass. This can result

in small amplitude differences when switching from the 5 MHz filter to nar-

rower filters. Relative responses using the 5 MHz filter are not affected. To determine the amount of error (if any), make an External Tracking Generator measurement using first the

5

MHz

filter and then the 300 kHz filter (the

300

kHz filter is symmetric about its peak response). Note the difference and

correct any absolute power measurements that you make with the

5

MHz

filter by that amount.

Setting the External Tracking Generator Amplitude

In many cases, you may want to increase the -48 dBm ( -1.26 dBmV for Option 01) External Tracking Generator output level. For instance, when using the 5 MHz resolution bandwidth filter, a -48

dBm (-1 -26 dBmV for

Option 01) signal is hidden in the instrument noise floor.

1.

To reset the output amplitude, press the DEMODfrG Menu key (DEMOD for the 2714).

2. Select item 5, TG FIXED

LEVEL.

Following the on-screen prompts, enter

a new value of

-

10.0 dBm (+38.8 dBmV for Option 01).

3.

Press DEMODnG (or DEMOD) to return to the spectral display. Notice that the new amplitude value is now shown at the lower left of the screen.

4.

Ensure that a cable with the appropriate impedance is connected from the TG OUTPUT connector to the RF INPUT input of the spectrum analyzer. Activate the video filter and reset the reference level to

+I

0

dBm (+58.75 dBmV for Option 01).

The combined External Tracking Generatorlspectrum analyzer frequency

response across the entire input frequency range of the spectrum analyzer is displayed. You may find that the flatness of the response varies slightly as you change the External Tracking Generator output level. This is normal. However, any variation in flatness can be removed

like this:

a

Establish the test parameters including center frequency, span, resolu-

tion bandwidth, reference level, and External Tracking Generator output. Conduct all measurements in the B,C MINUS A mode. This approach

subtracts out the variations in combined External Tracking Generator1 spectrum analyzer response, leaving only the response of the device.

w

Connect the TG OUTPUT to the RF INPUT of the spectrum analyzer, and save the resulting sweep in the

A

Insert the device to be tested.

rise above the A sweep. Note that the indicated

TG

output amplitude

has not changed.

NOTE

The

TG

output level is not calibrated

when

TG

Variable Level

is

active.

When the variable level control is set above the fixed level,

it

is possible to

slightly compress the TG OUTPUT signal, which may cause some degrada-

tion of the second harmonic specification. This is normally not a problem with passive linear devices, but can result in some intermodulation products

with nonlinear components, and spurious radiation from active devices,

such as modulators or transmitters.

To

avoid these problems, we suggest

that you use the External Tracking Generator fixed level and instrument

reference level controls to move signals vertically on the screen rather than

using the variable-level feature.

6.

Now clear the A register and toggle the TG VARIABLE LEVEL to OFF.

Adjusting the

Tracking

The TG tracking

is

the amount by which the External Tracking Generator

output frequency is offset from the frequency currently being analyzed by

the spectrum analyzer. The tracking can typically be adjusted from

-5

kHz

to

+60

kHz. For most measurements, the tracking is not turned on

(tracking

=

0

Hz).

3-8

Operation

However, it is necessary to adjust the tracking to ensure the External Tracking Generator signal is centered in the instrument resolution bandwidth filter

when the following conditions occur:

rn

you take measurements with a very narrow resolution bandwidth filter the device under test creates a significant delay between its input and

output ports (a long cable)

1.

To see how the tracking adjustment works, first set the center frequency and span as follows:

The 3 kHz resolution bandwidth is automatically selected, and the

display is a single horizontal line at approximately -1

2.

Save the display in register

A.

3. Press DEMODRG (DEMOD for

TG

tracking.

4.

Press a

MENU

key to return to the spectral display. It is unchanged

except for the message

TRKG

OHZ

at the lower right of the screen.

5.

Turn the FREQIMKRS knob several clicks clockwise. The indicated tracking should change by approximately 30 Hz per click, but nothing

else happens.

6.

Continue turning the knob clockwise until the D-register sweep decreases

6

dB relative to the A sweep.

7.

Now turn the knob counterclockwise until the D-register sweep again decreases

6

dB.

The

indicated tracking should change polarity. You

have offset the

TG output to the 6 dB down points of the 3 kHz resolu-

tion bandwidth filter.

Whenever you make measurements with the 3 kHz or 300 Hz filter, always

peak the response with the tracking control to ensure you are measuring the maximum signal. Further, whenever you use the 3 kHz or

300

Hz filter to test a device that imposes a significant group delay on the received signal (such as a long cable), vary the tracking to ensure the instrument is correctly

peaked. Because the External Tracking Generator signal is delayed, it lags behind the spectrum analyzer frequency by an amount that depends on the

sweep rate and the group delay.

8. Unsave (clear) the A register.

Using

External

Amplification/Attenuation

It is possible to insert another device such as an impedance matching network, attenuator, or amplifier between the output of the External Tracking Generator and the device under test. You can account for the gain or attenuation (and impedance change) introduced by the device. The altered output level appears on screen. This feature is a valuable aid whether recording data photographically, with a printer or plotter, or over the GPIB.

For instance, you

may

want to drive the device under test with a

+

10

dBm

(58.75

dBmV for Option

01)

signal. You can do this by setting the output of

the External Tracking Generator to

-

dBm

(38.8

dBmV for Option

and

inserting a

+20

dB amplifier between the External Tracking Generator and the device under test. In another case, you may wish to drive the External Tracking Generator at the full output of

0 dBm

(+46.8

but insert an external impedance matching pad to produce a better standing

wave ratio
