Waveform amplifier is a very handy piece of equipment to have in the lab. Most function generator, pulse generator, and arbitrary waveform generator output voltage are limited to about 10V. Function generator output resistance is typically 50 ohm, making it not suitable driving low resistance (high current) load. For applications require higher voltage or higher current or both, a waveform power amplifier is required. For applications require to drive heavy load, the waveform output resistance must be very low (e.g. less than 1 ohm). Similarly some applications require to drive high capacitance, a laboratory power amplifier is needed. The TS200 is a high voltage and high current amplifier for general laboratory and bench testing. It can output up to 70V (Option 3) or can drive more than 3A (Option 0). See TS200 datasheet for additional information
Figure 1 shows the functional equivalent diagram of the TS200 lab amplifier. It features
a selectable AC or DC coupled input. It also feature an adjustable DC offset voltage
output which is useful for LDO PSRR and line transient response testing. Two versions
of the TS200 are available, the A-

Figure 2 shows how to amplify a function generator to drive heavy load or large capacitance.
It uses the TS200 wideband power amplifier. The function generator or pulse generator
output is connected the TS200 modulation input. The TS200 output is connected to
the load. Typically, the TS200 DC Offset or DC output voltage is set to zero and
input modulation is set to DC-

The TS200 modulation output can be AC-
In summary, a function generator produces the desired signal waveform and the TS200 amplifies the signal to drive high current load or high capacitive load. The TS200 amplifier is flexible enough to work with a variety of function generators, pulse generators, and arbitrary waveform generators.
