Measurement system  －Voltage source for control equipment, bias voltage source for sensors, etc.－

Example: Light-emitting diode

By using it as a bias power supply, the SN ratio of the detection signal is improved.
When detecting the signal of a light-emitting diode, the detection signal varies greatly due to the influence of the bias voltage source.
Using a low-noise bias power supply is extremely important to improve the detection accuracy of small signals (such as biological signals).

Measurement example

Comparison of detection signals with bias voltage applied.

A comparison between a general linear power supply used as a bias voltage source and the LP6016-01 power supply is shown in the following block diagram.

 Product testing  －Used as control power supply and reference power supply for testing electronic components－

Example: Crystal oscillator

By using it as a control power supply, frequency variation can be reduced.
When evaluating the phase noise, frequency accuracy, frequency stability, etc. of a crystal oscillator, the stability of the control voltage source is a factor affecting the evaluation results.
Therefore, evaluating VCXOs (voltage-controlled crystal oscillators) with a precision power supply is particularly important.

Measurement example

Frequency measurement of VCXO 〜Output frequency comparison via control power supply〜

The charts below show comparison data between a general reference power supply and the LP6016-01 used as a VCXO control voltage source.
※The Δ frequency in the chart represents the difference displayed with the output frequency (approx. 30 MHz) at control voltage Vb = 1.000V as the reference.
