PREFACE

This manual (VOL.2) describes how to test the performance of the R3267 Series.

A separate volume (VOL.1) describes the operations, performance and remote programming of the R3267 Series.

(1) Configuration of this manual

1. Performance Verification	Describes how to test performance.

(2)Typeface conventions used in this manual

•Panel keys and soft keys are printed in a contrasting typestyle to make them stand out from the text as follows:

Panel keys: Boldface type	Example: FREQ, FORMAT
Soft keys: Boldface and italic type	Example: Center, Trace Detector

•When a series of key operations are described using a comma between two keys.

•There are various soft menus used to switch between two states such as ON/OFF and AUTO/MNL. For example, when turning off the Display ON/OFF function, the annotation "Display ON/ OFF(OFF)" is used.

When switching the RBW AUTO/MNL function to MNL, the annotation "RBW AUTO/MNL(MNL)" is used.

1.1 Preparation

1 PERFORMANCE VERIFICATION

This chapter explains how to check the R3267 Series. We recommend that you have a copy of the performance check sheet with you when performing these checks. If a problem occurs with the R3267 Series, contact ADVANTEST service center with measurement data filled out on the performance check sheet (including the model, serial number and so on). For information on how to ship the R3267 Series for repairs, refer to Section 1.5.3, "Transporting" in Vol.1.

NOTE: Perform the CAL ALL before starting this performance verification tests.

1.1Preparation

This chapter decribes the instruments using on this performance verification tests.

NOTE:

1.The R3267 Series to be tested should be warmed up for at least 30 minutes before starting tests. Any additional instrument used for this performance verification tests should be warmed up as appropriate.

2.Make sure that the test instrument used meets its own published specifications and that all connectors are clean, before starting test. All connectors should be firmly connected.

1.2.6IF Gain Uncertainty

This section explains how to check IF gain errors in the RBWs of 1 MHz, 300 kHz and 3 kHz. If the reference level is reduced, the IF gain is increased. The IF gain error can be measured if you deduce the input level in steps of 1 dB or 10 dB in order to reduce the reference level in steps of 1 dB or 10 dB as in the input level. In addition, the frequency reference source signal of the generator is supplied from the spectrum analyzer.
