A new architecture for signal analysis

The 2309 is a new concept in frequency selective level measurement
offering broadband frequency coverage between 100 MHz and

2.4 GHz.

The 2309 has many advantages over conventional swept tuned spec­trum analyzers particularly in terms of speed, accuracy, dynamic
range and detector linearity that together add up to a revolutionary
improvement in measurement capability for applications including
amplifier intermodulation testing, attenuator calibration and VCO
noise measurements.

The instrument uses a direct frequency conversion system followed
by a highly linear patented 1 bit bandpass sigma delta converter
operating at an IF of 10.71 MHz. In this way it is possible to make
faster, more repeatable and precise absolute or relative signal and
noise power measurements.

Automated Intermodulation measurement

The 2309 includes an applications mode featuring automated inter­modulation measurement functions ideal for both amplifiers and
frequency converting devices. This mode provides either user
defined or automatic measurement of a selected range of
intermodulation products. This simple to use mode is both fast and
very accurate. All hardware set-ups are automatically calculated
which ensures that the intermodulation products measured are
always a function of the device under test and not the test
instrument. The user is no longer required to make careful calcula­tions in order to find the optimum operating point for the instru­ment thus ensuring valid results are obtained every time. The
results can be displayed as a table of values or as a spectral trace. In
either case the results are verified against a test limit.

Speed

The 2309 is able to make narrow band measurements over 100 times
faster than even the best examples of swept tuned spectrum analyz­ers.

The speed advantage may be used directly to improve test through­put or used to convert into improved sensitivity level by using nar­rower frequency resolution for the same measurement speed.

Noise

A low noise local oscillator is used offering excellent close to carrier
spurious and SSB phase noise characteristics. This makes the 2309
ideal for making SSB phase noise and spurious measurements on
VCOs and synthesisers.

By avoiding the usual 'Up Down' mix techniques used in convention­al spectrum analyzers, the noise contribution from the local oscillator
is minimized thereby reducing measurement uncertainty.

High Sensitivity

The noise of the LO is closely matched to the performance of the A
to D converter giving a maximum sensitivity of typically

-153 dBm/Hz or -167 dBm when using the narrowest measurement
bandwidth available (0.04 Hz).

Dynamic Range

The third order intermodulation specification of typically <-90 dBc
for 2 tones of -26 dBm at the mixer input allows high performance
intermodulation measurements to be made.

The accuracy of the converter in making ratiometric measurements
ensures that the intermodulation product levels are accurately record­ed without the usual scale errors experienced with some spectrum
analyzers.

Unparalleled Figure of Merit (FOM)

With a mixer TOI (third order intercept) of typically +28 dBm and a
NF (noise figure) of typically 21 dB, the 2309 has a FOM of
+7 (TOI - NF). Unlike other A to D techniques, this instrument
obeys the normal 3:1 improvement in 3rd order intermodulation
products with decreased input level.

High Power

The high power input on the 2309 allows direct measurement on sig­nals up to 50 W (40 W continuous). This eliminates the need for
external high power attenuators and their uncertainties such as fre­quency and thermal responses.

Attenuators and Switches

Combining superb linearity, high marker resolution and low noise,
the 2309 is capable of making excellent attenuation measurements.
With a scale linearity of 0.01 dB per 10 dB and 0.0001 dB resolution,
the 2309 can be used as an attenuator transfer standard. The low
residual floor noise of typically -153 dBm/Hz and narrow FFT based
filters allows the 2309 to make measurements over large dynamic
ranges. These properties are equally relevant for attenuator and RF
switch repeatability testing.

tool to enable insertion of measurement traces into standard office
PC packages. The software enables the capture of trace data from the
2309 using a PC with a standard GPIB card. The traces can be
inserted into word processed documents or graphics packages using
.OLE formatting. Once inserted into the document the traces can be
rescaled, text and markers added and colors changed.

MIPlot is supplied as an optional accessory and is an excellent tool for
report generation or for presentation of results to large groups of peo­ple.

Level Accuracy

With a total measurement error of <0.5 dB to 1 GHz, the 2309 is ideal
for direct power measurement of transmitters. The excellent scale
linearity allows accurate measurement to be made over a wide power
range.

External Processing of Digitized IF Data

With the data cable, Aeroflex part number 43139/401, connected to
the Auxiliary I/O port on the rear panel of the 2309, digitized IF data
is extracted from the instrument using the National Instruments PCI

- 6534 digital I/O card and appropriate PC-based software. The cable
and digital I/O card can be supplied as accessories. With this config­uration, up to 10 seconds of data can be acquired, at a rate of up to 5
MByte/s for processing on a PC.

GPIB Control

Measurement speed in production environments is vital. The 2309
can be configured with the minimum of GPIB control commands.
The instrument is rapidly set up to pre-determined values or sensi­ble presets. All GPIB programming uses SCPI-like commands and
is based on the MEASURE, READ, FETCH structure. This means
that programs can be written quickly using high level commands
without needing an in-depth knowledge of the instrument.

Cost of Ownership

To minimize cost of ownership, careful consideration has been given
to the design and assembly of the 2309. The recommended calibra­tion interval is 2 years. An accurate internal 400 MHz calibrator pro­vides day to day alignment. A module exchange policy is used for the
repair of major assemblies. These assemblies are fully calibrated. As
a result, repairs can be carried out in the shortest time possible.

The use of FLASH memory and software download via the RS-232
interface means the 2309 can be upgraded without having to remove
its covers.

Printing Made Easy

By connecting directly to the parallel printer port interface, measure­ment results and trace data may be sent to any parallel printer which
is compatible with the HP PCL printer language PCL3 or higher (eg
HP DeskJet/LaserJet)
