1. INTRODUCTION
1.1 GENERAL
Tracking generator TR4153A/B (this nit) is a sweep oscillator connected
to the ADVANTEST spectr m analyzer (main nit).
Table 1-1 lists the spectr m analyzer connected to this nit and the
meas rement freq ency range.
Combined se of the tracking generator and the ADVANTEST spectr m analyzer
allows direct reading of the freq ency characteristic of the DUT within
the freq ency range depending on that of the main nit. In this case, a
dynamic range of 80 dB is obtained on the CRT of the main nit. Moreover,
a dynamic range of approximately 110 dB can be obtained by changing the
reference level on the CRT display.
Table 1-1 Connectable Spectr m Analyzer and Meas rement Freq ency Range
Spectr m analyzer Meas rement freq ency range
TR41 31 /E 100 kHz to 2 GHz
The normalization feat re of the spectr m analyzer (TR4131) main nit can
eliminate the freq ency characteristic of the meas rement system, which
permits direct reading of only the freq ency characteristic of DUT.

USER'S MANUAL
2.2 OPERATION METHOD
Fig re 2-6 Direct Reading of Freq ency Characteristic (3)
(1) Dynamic range
The dynamic range of meas rement is limited by the maxim m o tp t
level and white noise level of this nit. To widen the dynamic range,
red ce the IF band width of this nit to lower the noise level.
Since the tracking signal leaks into the main nit (T.G. leakage),
noise may not be red ced to the desired level if the resol tion of
this nit is increased to the maxim m val e. T.G. leakage provides a
dynamic range of -110 dBm (at an o tp t level of 0 dBm). Therefore,
meas rement can be done if the stop band of the filter ca ses
atten ation of approximately 110 dB. To prevent T.G. leakage, se
well-shielded cable cables and do not bring these cables close to each
other.
When the IF band width is red ced, pay attention to the following:
(a) The RBW (resol tion band width) of the TR4131/E is set to 30 kHz or
less, the tracking error (difference between o tp t freq encies of
this nit and main nit) ca ses a level error. Accordingly, it is
necessary to set RBW of the main nit to 1 kHz and to adj st the
tracking error by t rning the half-fixed vol me FREQ ADJ knob before
starting meas rement so that the level indication on the CRT screen
becomes maxim m.
(b) The CRT display cannot display dynamic ranges greater than 80 dB
therefore, switch reference levels of the CRT display. Pay
attention to level s ppression ca sed by excessive inp t in the
primary mixer in the inp t block of the main nit.
(2) Time response
"UNCAL" is displayed to indicate whether the level displayed on the
CRT screen is correct. This indication, however, has no meaning when
freq ency characteristics are meas red sing this nit.
2 - 8

TRACKING GENERATOR (TR4153A/B)
USER'S MANUAL
2.2 OPERATION METHOD
"UNCAL" indicates whether the IF filter responds correctly to indicate
the level according to the combination of SWEEP TIME/DIV., SPAN, and
BANDWIDTH switches of the main nit. For the nit holding a constant
level like this nit, the level may displayed normally even if "UNCAL"
is displayed.
If the signal which is s pplied from the o tp t terminal of DUT to the
main nit changes abr ptly, the IF filter of the main nit stops
responding. Pay attention to the response by DUT itself.
If the SWEEP TIME/DIV. switch is operated, the IF filter and DUT
respond normally providing the characteristic on the screen does not
change. If the characteristic changes when the SEEP TIME/DIV. switch
is operated, delay the sweep time or make the span (freq ency sweep
width) narrow.
(3) Normalization f nction
The normalization f nction is sed to compensate for the freq ency
characteristic of the TR4131/B and to compare waveforms displayed on
the CRT screen. The proced re for meas ring the high freq ency cable
insertion loss is explained below as an example.
(T) Connect the TR4131/E and TR4153A/B in the system, except the cable,
to be tested. (See Fig re 2-7.)
(The freq ency characteristic meas red in this system involves the
cable insertion loss and freq ency characteristic of the TR4131/E;
the cable insertion loss concerned is obtained according to this
freq ency characteristic.)
