DDS sweep generators Model
4007B and Model 4013B generate
sine and square waveforms from 0.1 Hz
to 7 MHz and 0.1 Hz to 12 MHz, respectively.
They output triangle/ramp waveforms
from 0.1 Hz to 1 MHz and provide
variable output voltages from 0 to 10V
pk-pk into 50Ω or 20V pk-pk into an
open circuit. Both models also provide
linear and logarithmic sweep functions,
variable dc offset from −4.5 to +4.5V
(into 50Ω), and adjustable 20% to 80%
duty cycle up to 1 MHz for square and
triangle waveform output. A sync output
is accessible on the front panel for outproductroundup
GHz and 0 to 75 dB with a 5-dB step
size from dc to 67 GHz. Depending on
the configuration, the price range of the
product is $5000 to about $10,000.

Digital power meters
from Yokogawa boast
0.1% accuracy
↘
The WT300 series of digital
power meters deliver basic measurement
accuracy of 0.1% of reading +
0.2% of range, low-current measurements
down to 50 μA, and high-current
measurements up to 40A RMS. The
instruments measure all ac and dc
parameters and have a dc measurement
range of 0.5 Hz to 100 kHz. A wide
range of communication interfaces
allows power meters to be integrated
into laboratory test benches or automated
test setups on production lines.
USB and GPIB or RS-232 interfaces are
standard, while Ethernet is optional.
The basic price for the WT310 is $2210;
pricing for the WT330 starts at $3875.

TDK-Lambda extends
programmable supply
line
↘
The Z+ series of programmable
dc power supplies now includes
models that provide 200W of output
power with an output voltage range of
0 to 100V dc and output currents of up
to 20A. The standard models are only
3.27×2.76 in., and six units can be
installed in an optional 19-in. rack
housing. Options for front-panel output
jacks and multiple-unit housings are
available for bench applications. All
models operate in constant-current or
constant-voltage
mode from an
input of 85 to
265V ac. They
also feature USB,
RS-232, and
RS-485 interfaces,
with optional
LAN, GPIB, and
isolated analog programming. The base
price for the power supplies is $1185.

ProPlus 1/f noise
system integrates
dynamic signal analyzer
↘
The NoiseProPlus 9812D waferlevel
1/f noise-measurement system
delivers accurate measurement up
to 10 MHz, while its built-in DSA
eliminates the need for external signalprocessing
equipment. The system measures
low-frequency noise characteristics
of on-wafer and packaged semiconductor
devices, including MOSFETs,
BJTs, JFETs, diodes, and diffusion resistors.
The 9812D handles up to 100V
from the source-measure unit for highvoltage
and/or low-current (
