Spectrum Analyzers FSEA, FSEB, FSEM, FSEK
20 Hz to 40 GHz
High-performance analyzers for digital mobile radio and universal applications
FSEK30 (photo 42756)
Brief description
In addition to measurement functions for digital communication systems, such as 2 µs sweep time in ZERO SPAN mode, pretrigger and trigger delay, gated sweep and adjacent­channel power measurement, these spectrum analyzers feature a wide dynamic range, a very low measure­ment uncertainty of 1 dB and a low­noise synthesizer.
FSE analyzers have low inherent noise and a wide dynamic range, so that for instance measurement of GSM power ramps is no problem.
An extremely wide intermodulation­free dynamic range of 110 dB (with 10 Hz resolution bandwidth) ensures reliable measurements on highly lin­ear amplifiers as well as correct anal­ysis of broadband complex signals.
From the available frequency ranges, the basic models 20 and the high-per­formance models 30 the right instru­ment can be chosen for every applica­tion. Models 20 can easily be upgraded to give the full range of func­tions of models 30.
To ensure correct measurement of time variants or pulse-modulated signals, the FSE features digital resolution fil­ters (10 Hz to 1 kHz) with a response corresponding to that of analog filters. It additionally provides FFT band­widths down to 1 Hz (models 30).
Main features
• Resolution bandwidths 1 Hz (up to 10 MHz), adjustable in steps of
1/2/3/5/10
• Displayed noise floor down to
160 dBm (FSEA)
Type Index
• 3rd-order intercept point >+15 dBm
• 1 dB compression point of RF input
>+10 dBm
• Phase noise at 20 kHz from carrier:
down to 123 dBc (FSEA)
• Intermodulation-free dynamic range 110 dB
• Measurement uncertainty up to 1GHz: 1dB
• Headphones connector and built-in loudspeaker for AM/FM
• Internal RF trigger for GATED SWEEP measurements
• Speed records: – Shortest FULL SPAN sweep time
is 5 ms (for 3.5 and 7 GHz span) with a fully synchronized sweep – added speed is not at the expense of frequency accuracy but even enhances it
– Shortest ZERO SPAN sweep time
is 1 µs (100 ns/div) – ideal for high-resolution measurements on pulse edges
– More than 20 sweeps/s – an
optimal prerequisite for fast alignments or applications in pro­duction

Spectrum Analyzers FSEA, FSEB, FSEM, FSEK
From AF to microwave
FSEM/K21/31 (corresponding to FSEM/K20/30 with option FSE-B21) allow frequency range extension by means of external mixers. Continuous automatic signal identification, which is used to suppress unwanted image frequency bands and mixture prod­ucts, ensures fast and easy measure­ments. Due to the built-in diplexer, three-port as well as two-port mixers can be used.
The external mixer measurement func­tion features great ease of operation:
• Definition of frequency range and harmonics by selection of a waveguide band
• Definition of all important parame­ters for each waveguide band separately
• Frequency-dependent consideration of mixer conversion loss
• Storage of parameters on hard disk
Measurement functions
• Up to 8 markers
• Marker functions for the direct measurement of – phase noise and
phase power density
– NEXT MIN/PEAK, NEXT MIN/
PEAK RIGHT, NEXT MIN/PEAK LEFT
• Frequency counter with selectable resolution
• LOW NOISE, NORMAL and LOW DISTORTION modes to cater for low-intermodulation and low-noise operation
• Plotting or printout in background operation or file saving in standard graphic format
• Simultaneous display of four traces
• Selectable colour setup
• Numerous level and frequency lines
• Split-screen display with independ­ent windows
• Quasi-analog display
• Frequency zoom
Type Index
•Limit lines
• User-configurable menu and key­board macros
• Adjacent-channel power measure­ment for up to 7 channels
•RMS detector
Operation
A combination of hardkeys and softkeys makes for extremely fast and easy operation. The operating conven­ience based on a wide variety of eval­uation routines and marker functions can be accessed via the menus. Com­plicated tree structures could be avoided by using menus of lateral structure and fixed control keys. Com­plete setups and traces, limit lines as well as macros can be stored on the hard disk or on floppy disks.
