TS200

Modulated Power Supply
The TS200 Modulated Power Supply is a
unique instrument for many test and
measurement applications such as LDO PSRR
measurement, battery simulator, op amp
CMRR measurement, function generator
amplifier, transient response test, four-quadrant
power supply, lab power amplifier and more.
The modulated power supply is designed for
bench test and measurement. It can output DC
or AC voltage or both. For example, it can
output a 3.3V DC voltage with a 300mVpp AC
sinewave riding on top of it. The TS200
features a modulation input to modulate the
output to produce any desired waveform.
PSRR Measurement
TS200 is ideal for power supply rejection ratio
or PSRR measurement. PSRR is commonly
tested for LDO regulators, op amps, audio
amps, etc. TS200 is especially powerful for
LDO PSRR testing at high load current (See
Application Section). TS200 can also test op
amp PSRR and CMRR. Conventional regulator
PSRR test techniques such as capacitor or
inductor coupled unable to support high LDO
load current (i.e. >1A). Various PSRR
measurement techniques are outlined below in
this datasheet. The application section shows
how to measure power supply rejection using
network analyzer. The TS200 is designed to
work with network analyzers such as Omicron
Lab Bode 100, AP Instruments (Ridley) model
300, Agilent 4395A, and Audio Precision
SYS2722
Waveform Amplifier
TS200 is also ideal as a function generator
amplifier for amplifying waveforms. It can
drive high current or high power or high
voltage load. The TS20 high voltage amplifier
can output up to 70V. As a waveform
amplifier, it accepts AC or DC input from a

function generator and amplify the waveform
by a factor of 10. TS200 is also great for pulse
amplifier and laboratory power amplifier.
Battery Simulator
TS200 modulated power supply can source or
sink current. It can be used as a battery
simulator. The TS200 has a variable DC output
that can easily simulate battery voltage
changes. Thus it is great for battery charger
testing such as those in battery operated
portable electronic systems.
Four Quadrant Power Supply
TS200 is a four quadrant power supply,
sometime referred to as bipolar power supply.
It can output both positive and negative voltage
and it can source and sink current up 3.0A. It is
sometimes refer to bipolar operational
amplifier
