High-performance spectrum analysis

By taking full advantage of the latest RF technology, the R3681 can make measurements over a wide dynamic range.

Measurements are performed over a wide dynamic range:

●Average display noise level: -158 dBm (typical 1 GHz)

●Built-in preamplifier on: -168 dBm (RBW = 1 Hz, 1 GHz)

●1 dB compression point: +10 dBm (typical 200 MHz to 3.5 GHz)

●Third-order intercept (TOI): +26 dBm (typical 2 to 3.5 GHz)

●Signal purity (at 800 MHz)

10 kHz Offset: -120 dBc/Hz or more

1 MHz Offset: -140 dBc/Hz or more

10 MHz Offset: -155 dBc/Hz or higher

Built-in attenuator, 5 dB level (standard)

1 dB level attenuator (OPT.14)

●Resolution bandwidth (RBW): 1 Hz to 10 MHz (Sequences 1. 2. 3. and 5)

Display dynamic range: 10 dB/fixed

0.1 to 1 dB/div. (0.1 dB steps)

1 to 20 dB/div. (1 dB steps)

Steepness shape factor

Approximately 3 times the conventional value. This reduces the resolution of carrier near-field measurements.

■ (AC+DC) AC measurement

The true-RMS measurement of AC allows (AC+DC) measurement

capability for measuring the true effective value of a

distortion wave including the DC components.

■ Internal high capacity data memory

Up to 10000 measurement data can be stored in internal data

memory after operation along with the measurement function

information. This allows measurement for different measurement

functions.

■ Parameter memory function

Up to four measurement conditions can be stored in internal

flash memory as User-0 to User-3, and then any one can be

activated during measurement.

■ Measurement of low power 2WΩ/4WΩ resistance

The low power 2WΩ/4WΩ resistance measurement allows a 1/

10 measurement current setting to minimize the effect of heat

generation during resistance measurement on the component

being tested.

■ Up to seven kinds of operations

Seven kinds of operation (NULL, smoothing, scaling, dB/dBm,

comparator, and MAX/MIN) can be performed on the measurement

data.

■ Optimum remote control capability for system use

The standard GPIB and RS232 interfaces facilitate automated

measurement. Input terminals are available on both the front

and rear panels for easy rack installation.

■ LONG-IT function for averaging of repetitive signals

(DCV, DCI)

The LONG-IT function allows averaging of accurately repetitive

input signals by measuring the same signal twice during

any 10ms interval from 100ms to 60s. This simplifies measurement

of the standby current (average) of PDC/PHS, etc.

■ High performance and high speed sampling

The high performance DMM, with a maximum “319999” (5 1/2

digits) display and ADVANTEST’s unique multiple-slope integral

A/D conversion, is capable of high speed sampling at 1000

samplings/sec in BURST, 100/sec max. in FAST, 20/sec in MED,

and 5/sec max. in SLOW modes. The result of measurement is

stored automatically in internal memory and recalled for later

use. Various operations may be applied to the measured values.

■ Improved AC measurement performance

The AC measurement performance has been further improved

with the measurement ranges of 300mV to 700VAC and 3mA to

3A at basic accuracies of ±0.06% of reading (VAC) and ±0.2%

of reading (AC). The response time is increased 2 to 3 times

while the frequency characteristics are expanded in both the

high and low ranges.

10ms steps between 100ms and 60s for averaging

repetitive signals.

equipment

■ External trigger input, end-of-measurement signal

output (standard)

R6552 Series

5 1/2-digit DMM with a Wide Range of

Applications

The R6552 Series is a digital multimeter designed for system or

bench use with the maximum display of 319999, featuring

GPIB and RS232 interfaces with full remote control capability.

It is capable of measuring DC voltage/current, AC voltage/

current, 4- or 2-wire resistance, low/power 4- or 2-wire resistance,

(AC+DC) AC voltage/current, frequencies, and diodes.

ADVANTEST’s unique multi-slope integral A/D conversion

method ensures high speed and high precision measurements.

The AC voltage/current measurement uses the true-RMS (true

effective value) method while the (AC+DC) AC voltage/current

measurement allows measurement of a true effective value of

the distortion wave including the DC components. In addition

to the FAST/MED/SLOW sampling modes of the conventional

models, the R6552 has BURST and LONG-IT modes as well.

Generates SDH/SONET Frame Patterns Close to Actual Data

For evaluating optical transport equipment, E/O and O/E modules

Frame-level testing is required for O/OE and E/O testing of SDH/SONET systems.

The D3186 Pulse Pattern Generator, in addition to having a large WORD memory

of 8 M bits in length, provides a frame-level test in the STM frame header section.

The D3186 Pulse Pattern Generator, in addition to having a large 8 M-bit WORD memory,

provides the optional functions of inserting a WORD pattern into the header portion

of the STM frame and inserting an arbitrary PRBS into the payload portion,

Extensive Analysis Functions

Sweep Function

The Q8384 displays the optical frequency on the horizontal axis; this is ideal for measuring

the grid frequencies of standardized wavelengths specified by the ITU-T (International

Telecommunication Union Telecommunication Standardization Sector).

Measuring the noise figure of a fiber-optic amplifier The Q8384 improves the noise figure

of a fiber-optic amplifier by enhancing the dynamic range, polarization correlation,

level accuracy, linearity, and accuracy of wavelength resolution settings.

As well as applying curve fitting and other features, the Q8384 realizes

high-precision noise figure measurements at the touch of a button.

Since the Q8384 can accurately determine the ASE signal level of DWDM signals

that are multiplexed at 10-minute intervals.

Since the Q8384 can accurately determine the ASE signal level of DWDM signals

multiplexed at intervals of 50 GHz (0.4 nm) or narrower, it not only performs accurate noise figure measurements,

but it can also accurately measure the noise figure of DWDM signals multiplexed at intervals of 10 minutes.

It not only performs accurate noise figure measurements,

but also displays multiple lists of measurement results at the same time.

WDM Analysis Functions

The Q8384 can display up to 256 wavelength peaks and power levels of WDM signals.

It displays the deviation of the wavelength and power level from the

ITU-T channel spacing or reference signal as well as the absolute value.

Alternate Scanning Function

The Q8384 can display two sets of measurements under different setup conditions in two windows.

These windows are always rewritable using the Q8384’s alternate scan feature.

With this feature, users can make detailed measurements of signals in a specific wavelength

band while monitoring the entire wavelength region of the WDM system.

Superior Fundamental Performance

10 pm High Wavelength Resolution The Q8384 achieves a wavelength resolution bandwidth

of up to 10 pm by using a newly developed monochromator system.

This makes it possible to measure and evaluate the sidebands of 10 Gbps intensity-modulated optical signals,

a task previously impossible with conventional spectrum analyzers.

20 pm high wavelength accuracy

Calibrated with the built-in calibration light source (option 25), the Q8384 achieves wavelength

 measurement accuracy of ±20 pm in the C-band wavelength range from 1530 to 1570 nm.

The Q8384 achieves wavelength measurement accuracy of ±20 pm in the

C-band wavelength range of 1530 to 1570 nm and ±40 pm in the L-band wavelength range of 1570 to 1610 nm.

It enables accurate characterization of laser diodes and filters used in DWDM transmission systems.

The Q8384 can also accurately measure the wavelength spacing of WDM signals

because of its ±10 pm wavelength linearity over the 1530 to 1570 nm wavelength range.

50 dB (±0.1 nm)/60 dB (±0.2 nm) Wide Dynamic Range

In DWDM systems, signals need to be WDMed at intervals of 50 GHz (0.4 nm) or less.

Separating and measuring these closely spaced signals requires an optical spectrum analyzer with excellent dynamic range.

The Q8384’s dynamic range of 60 dB or more at 0.2 nm makes it ideal for this task.

With a dynamic range of 50 dB or more at 0.1 nm, the instrument can support future DWDM systems with closer signal spacing.

+23 dBm (200 mW) high-power direct input The Q8384 can directly measure high-power

signals from fiber amplifiers or pump laser diodes without attenuation.
