Technical Characteristics

The usable frequency range of the new spectrum
analyzer HM5012- and HM5014-
2
above 1GHz. The available resolution bandwidths are 9kHz,
120kHz and 1MHz.
The high stability frequency generation is based on a
phase-locked direct digital synthesizer (DDS) with a TCXO-
base oscillator, resulting in improved accuracy, stability
and repeatability. Frequency values are set via a new
integrated front panel keypad or by means of a rotary dial.
All other functions are set in the same manner.
The frequency spectra is digitized and stored in real time
and displayed with a resolution of 2000 sample points over
the entire screen. The dynamic range of the analyzer
display is 80dB max.
The screen will also display all selected frequency settings
and the marker results, other parameters are indicated
with LEDs. Other unique features of this spectrum analyzer
are the extensive EMC measurement capabilities. EMI
pre-compliance measurement including average, max.
hold and quasi-peak detection is an important application
use.
For the precise evaluation of the signals, a marker is
provided that will give an on screen readout for amplitude
and frequency. An additional advantage is that newly
acquired signals can be compared with the content of the
stored reference. Complicated and frequently used set
ups can be saved by use of the Save/Recall function.
HM5014- with Tracking-Generator
2
The Model HM5014- includes a tracking generator that
2
can be used to evaluate the frequency characteristics of 2
port devices, such as band pass filters. Frequency Range
is from 150kHz to 1050MHz. Output level is selectable in
0.2dB steps (keypad or rotary dial) from -50dBm to +1dBm.
The Interface
The Analyzers are supplied with an RS-232 interface for
PC communication and printout via PC. The optional HZ70
opto-isolator with fiber optic cable is available to isolate
the spectrum analyzer from interference effects and ground
loops.
The Software AS100E
The new HAMEG Spectrum Analyzer PC software provides
an easy to use communication link between a PC and
Subject to change without notice
is from 150kHz to
