5. SOLT Calibration Kits
Fairview Microwave unveiled a
series of short-open-load-through
(SOLT) calibration kits for use in
lab, test and measurement, and
RF and Microwave production test
applications. Fairview's expansion
of its VNA calibration kit line
consists of 12 models including
short circuit, open circuit, and
load kits (SOL), as well as short
circuit, open circuit, load, and
thru kits (SOLT). Interface options
include 2.4mm, 2.92mm, 3.5mm,
7/16 DIN, 7mm, N-Type and BNC.
Every model of VNA calibration
kits includes the required short
circuit, open circuit, loads,
and thru (model dependent)
components required for VNA
calibration.

1000 Voltage Sensors

7. GX3788 Multifunction 8. Positive Slope
Instrument
Equalizers

The DVC 1000 series of voltage
sensors for insulated nominal
voltage measurements in
rail traction and industrial
applications offers panelmounted voltage measurement
in a package measuring 29 x 51
x 89 mm (131.6 cm3). Designed
to measure a nominal voltage of
1000 VRMS, the series uses an
isolating amplifier, providing a
safety insulation voltage of 4.2
kV. DVC 1000 voltage sensors
are suitable for a broad range
of small-to-medium voltage
measurements in industrial
markets such as DC power supply
monitoring, EV chargers, and
battery-storage applications.

The GX3788 High-Performance
FPGA Multi-Function Instrument
combines A/D, D/A and digital
I/O functionality. The GX3788
is a user-configurable 3U
PXI hybrid-slot-compatible
instrument, with digital and
analog test capabilities. Suitable
for challenging functional test
applications, the instrument's A/D
channels can be configured as 8
differential or 16 single-ended
inputs, at sampling rates of up to
250 KS/s. Two-channel operation
can support a sampling rate of 1
MS/s. The D/A channels support
a simultaneous sampling rate
of 1 MS/s, while the digital I/O
channels are TTL-compatible and
can be programmed as inputs or
outputs.

Pasternack's latest positiveslope equalizers compensate for
gain variation in systems where
excessive losses may occur at the
low end of the frequency band.
They are suitable for a variety
of applications like aerospace
and defense, MILCOM and
SATCOM, test and measurement,
and wireless infrastructure.
The selection of positive-slope
equalizers consists of 18 models
operating over octave frequency
bands from 500 MHz to 40 GHz.
These 50-Ohm designs have fixed
equalizing values from 2 to 8 dB,
at the minimum frequency, and
produce an attenuated response
that increases linearly across the
frequency band.
