Low FM modulation distortion, low
spurious, high purity source for all basic
performance tests
VP-8130 series features long-life
electronic attenuator for all bands
· RF section employs electronic attenuator to achieve
the zreliable long life required for high speed
automated testing systems.
· Covers wide range from LW to VHF.
· Supports hi-fi receiver tests with low –60 dBc
spurious and 90 dB or more S/ N ratio.
Built-in direct digital synthesizer (VP-8133A)
FM/AM high purity signals
· The VP-8133A features a DDS in addition to
400 Hz/1 kHz internal oscillators to allow 1 Hz step
frequency response measurements from 20 Hz to
20 kHz.
· Low FM (0.01% or less) and AM (0.1% or less)
modulation distortion with –60 dBc non-harmonic
spurious for testing hi-fi receivers.
· Residual distortion of better than 90 dB (FM) and
65 dB (AM).
High 2 V output (19 dBm)
3
· High output from –133 to +19 dBm (50 Ω).
· 0.1 dB attenuator setting resolution for all ranges.
· Results can be celected in 7 units.
· Built-in output level sweep function.
· Built-in AM/FM stereo modulation
(VP-8132B/VP8122A)
makes it easy to configure measurement
instruments and set up optimal measurement
conditions. Switching signals and connecting
instruments is greatly simplified.
High 10 Hz RF resolution (10 kHz to 140 MHz)
· Frequency range of 0.01 to 280 MHz covers LW,
AM, FM and VHF TV bands to allow testing of
anything from hi-fi tuners, car audio and pagers to
communications equipment.
· 8-digit high resolution setting:
20 Hz (140.00002 to 280.00000 MHz) and 10 Hz
(below 140 MHz).
· Frequency sweep function provided as standard.
Space saving design simplifies
measurements
High-speed frequency settling, GP-IB interface
· Standard GP-IB interface with fast 70 ms frequency
settling time supports high-speed system
automation.
Flexible memory and interfaces
· An auto sequence function makes it simple to create
an automatic measurement system by combining the
SSG with a Panasonic audio analyzer, etc. No
external PC or controller is required. Standard
memory can hold up to 100 combinations of panel
settings.
· External control of other instruments and automated
test system peripherals is supported by a 2-port,
8-bit TTL I/O external control interface.
