IG-1700
Impulse Generator
11 Hz to 1 GHz
 |
Inexpensive calibration source
Accurate calibration signals to 1 GHz
Useful frequency and amplitude calibration source
Pulse repetition rate single or repetitive, internal or external, or
synchronized to the AC line
Fully programmable via the IEEE-488 bus
Lightweight/easy to handle
The Model IG-1700 Impulse Generator is a solid state RF impulse
generator covering the frequency range of 11 Hz to 1 GHz. The IG-1700
may be used as a calibration source for the R-110B or other wide range
receivers and may be integrated into the DSI-110, DSI-120, DSI-2020 and
DSI-200 systems. It provides impulses at repetition rates and amplitudes
selected by front panel controls or via the IEEE-488 bus.
The IG-1700 features an uncomplicated front panel with discrete LED
displays to indicate the pulse repetition rate and the actual output
amplitude in dBuV/MHz at 100 MHz. Provision is made for pulses to be
triggered by an adjustable internal time base (manually, externally, or
by the AC line). Pulse repetition rate and amplitude may also be
programmed via the IEEE-488 interface bus. Calibration curve is supplied
providing amplitude referenced to 100 MHz. |

RG-1000A
Raster Generator
X-axis range 100 Hz to 500
kHz
Y-axis range 20 Hz to 2 kHz

Separately controllable vertical and
horizontal synchronization channels.
Dual frequency displays
Tuning knob, keypad and vernier control for accurate frequency setting
Z-axis output channel with gain, offset and invert controls
Precision frequency synthesizers with stable clock to facilitate capture
of signals
Remote operation via IEEE-488 bus
Many signals that defy analysis by other means can be understood by an
operator when presented in a visual format. The RG-1000A Raster
Generator makes this possible. This instrument contains a unique
combination of digital and analog circuitry that allows conversion of
almost any repetitive electronic signal into a pictorial display. While
raster generators are commonly used for recovery of signals that are
similar to television transmissions, many other applications are
possible. EMI evaluation and telemetry monitoring are two examples.
The RG-1000A provides an X-axis range of 100 Hz to 500 kHz, and a Y-axis
range of 20 Hz to 2 kHz. Either output may be made to track the other at
a user selectable ratio, or tuned or set independently. All frequencies
are precisely synthesized from a master clock, and an added vernier
circuit allows continuous fine tuning. Adjustable gain, offset,
blanking, and selectable signal inversion are provided for the Z-axis
(video) channel. IEEE-488 bus control of all functions is a standard
feature. |

Synthesizer
Immunity
IEC61000-4-3
30 MHz - 1 GHz
 |
PC controlled RF synthesizer for
immunity testing matched to the requirements of IEC61000-4-3
and featuring automatic scanning to pre-programmed schedules. To make the
best use of the immunity test facilities for both compliance testing and
product investigations, several useful features have been developed.
These include:
-
Powerful EUT monitoring with real time
display correlated to field strength and frequency.
-
Sweep can be continuous or 'pause on
fault' or 'stop on fault'. Additional EUT excitation output, either
pulsed or continuous.
-
Flexible single frequency search mode.
Automatic ramping of field strength and fine control of frequency.
The system is controlled from any PC via a
Windows software package and serial port. No additional interface cards are
required. |
