TYPICAL APPLICATIONS
• High voltage device breakdown
testing
• High voltage component testing
• Insulation testing
• High voltage resistivity
measurements
• High energy physics research
Series 2290 High Voltage Power Supplies facilitate high voltage device and material testing, as well as
high energy physics experimentation. The Model 2290-5 5kV Power Supply provides voltage outputs
up to 5000V, and the Model 2290-10 10kV Power Supply offers up to 10,000V. The Model 2290-5 has
a 5mA current capacity, and the Model 2290-10 has a 1mA current capacity. These supplies measure
both output voltage with 1V resolution and output current with 1µA resolution. In addition to the
voltage and current output displays, a third display shows one of four settings: output voltage, voltage
limit, current limit, or current trip. These values can be set precisely with the front panel keypad. The
settings can also be programmed over the IEEE-4888 interface, or the output voltage can be set with
an analog control voltage.
Low Noise Ensures Accurate Low Level Measurements
Low output noise is essential when using sensitive measurement instruments to make leakage cur-
rent or high resistivity measurements. The maximum output ripple for the Model 2290-10 is less than
1V
RMS
. The maximum output ripple of the Model 2290-5 is 100mV
RMS
. Two selectable, internal filters
on the Model 2290-5 reduce the maximum output ripple to only 3mV
RMS
. Extremely low noise from
both power supplies enables sensitive measurement instruments to make accurate current measure-
ments down to picoamp levels.
Protecting User and Instrumentation
Series 2290 Power Supplies and a Model 2290-
PM-200 Protection Module protect both user
and instrumentation from hazardous voltages.
An interlock circuit built into the power supplies
can be used to ensure that the output voltage
is disabled if a high voltage test fixture access
door is open. In addition, all Series 2290 power
supplies have low voltage analog outputs to per-
mit safe monitoring of the high voltage and the
output current.
When low voltage measurement instrumentation
is used in the high voltage circuit, the protection
module safely clamps the voltage across the
instrument to a maximum value of 200V even
when a device under test (DUT) breaks down.
Thus, a Series 2290 Power Supply, Model 2290-
PM-200 Protection Module, and Keithley accesso-
ries provide all the elements for building a safe,
high voltage test environment.

High Voltage Power Supplies
Make Precise Current Measurements Lower Than 1µA
Use a sensitive Keithley measurement instrument, such as a Keithley SourceMeter
®
Source Measure
Unit (SMU) instrument, to measure current drawn by the device under test (DUT) that is below the
sensitivity of the Series 2290 Power Supplies. Keithley SourceMeter SMU instruments can provide
sensitivity as low as 0.1fA. The following diagram shows how the Model 2290-PM-200 Protection
Module protects the low voltage SourceMeter SMU instrument from high voltages when the DUT
breaks down. The leakage current of the protection module limits the measurement resolution to
picoamp levels, which is five decades more sensitive than the current measurement resolution of the
Series 2290 Power Supplies. Keithley can provide a complete high voltage test capability with the
most current measurement sensitivity available anywhere.
