Microwave Signal Generator SMP
Microwave signals in the range
from 10 MHz to 40 GHz
The basic models of the SMP cover the
following frequency ranges:
◆
SMP02/SMP22 (2 GHz to 20 GHz)
◆
SMP03 (2 GHz to 27 GHz)
◆
SMP04 (2 GHz to 40 GHz)
The lower frequency limit can be option-
ally extended to 10 MHz.
A modern frequency synthesis concept
with direct digital synthesis (DDS) is the
basis of:
◆
stable output frequency
◆
0.1 Hz frequency resolution
◆
fast settling after a frequency
change
High, levelled output power
All SMP models have been designed for
high output power without any compro-
mises:
◆
SMP02 (>+11.5 dBm)
◆
SMP22 (>+20 dBm)
◆
SMP03 (>+13 dBm)
◆
SMP04 (>+10 dBm)
The output levels specified are valid for
the upper frequency limit.
Excellent spectral purity
High spectral purity is ensured by the use
of YIG oscillators – up to 20 GHz without
any frequency multiplying:
◆
Harmonics
<–50 dBc typ. for f >1.8 GHz
◆
Nonharmonics <–60/54 dBc
up to/above 20 GHz
◆
SSB phase noise at
10 GHz <–105 dBc (1 Hz)
(10 kHz from carrier)
Versatile modulation
capabilities
AM, FM and optional
ϕM modulation
meet the high standards usually expected
of low-frequency generators only. The
large variety of options includes a high-
speed pulse modulator:
◆
AM (DC to 100 kHz)
◆
FM (DC to 5 MHz)
◆
ϕM (DC to 100 kHz)
◆
Pulse modulation with
on/off ratio >80 dB
Large choice of options for
user-specific configuration
A wide selection of options allows the
SMP to be configured economically to
meet today's and tomorrow's require-
ments:
◆
Pulse generator and pulse modulators
◆
Frequency extension 0.01 to 2 GHz
◆
RF attenuator
◆
Modulation generator up to 500 kHz
◆
Precision FM/
ϕM modulator
◆
OCXO reference oscillator
◆
Auxiliary interface
