QL564 SII

The QL series offers an unparalleled level of precision. Voltage and current are controlled using instrumentation quality 16 bit DACs enabling voltages to be set to 1mV resolution even at full output voltage. Indeed, The QL series II provides multiple ranges for increased current capability at lower voltages. A low current range provides an enhanced current setting and measurement resolution of 0.1mA. The QL series uses pure linear technology and offers unrivalled performance in terms of regulation, output noise and dynamics. Line and load regulation are close to the limit of measurement. Recovery time from transient current pulses is better than 50µs. Differential output noise is less than 350µV rms in CV mode and down to 20µA rms in CI mode. Common mode noise current (the noise current flowing between the output terminals and ground). <4µA rms.
