Heavy external loads should be avoided, which reach or exceed the device‘s nominal output current of 10mA on a longer time scale (minutes, hours). The outputs feature an internal programming resolution of 16 Bits (BS series) or 19 Bits (BSA series). This translates into these approximate resolutions:...

Special Functions, Cryo Supplies, PID Loop The BS Series supplies can be equipped with additional functions, which ease their use as cryogenic biasing supplies, e.g. for Gallium-Arsenide based low temperature amplifiers. Two banks of 5 channels each are provided in a BS 1-10 device fro such purposes.
FETs, and thus their Drain current and power dissipation constant. Such loops are provided in the BS series supply in case the corresponding option is chosen. 2 loops are implemented per device. The subsequent figure shows the wiring principle.

1.829V (red circle in fig. 7.5). The correct functionality of the loop can be monitored by checking the read back value of the loop voltage (being applied to the PID input at rear side), e.g. 1,502V in this www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884...
0,4V magnitude, during which the actual voltage will increasingly deviate from the set value. This represents a “smooth” transition from the set voltage to the limiting value. www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884...

+/-2K during the measurement. The voltage rise in the first third of time period is mainly due to a temperature rise of approx. 2K www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884...
+/-2K during the measurement. 9.2 BS Series Fig. 9.4: This figure illustrates the stability of an output channel at +10V, BS series, over a 1-day interval. Measurement device was a Fluke 8846A multimeter, 30sec. averaging per data point. The room temperature has been determined to be constant within +/-0.7K during the measurement.

Ambient temperature has been determined to be constant within +/-0.7K. Fluctuation Data (continued) Fig. 9.6: This figure illustrates the short term stability of an output channel at +10V, BS series, over a 10-minute interval. Measurement device was a Fluke 8846A multimeter, 0.5sec. averaging per data point. One measurement point was taken every second.
User Manual, Rev 2.60 Fig. 9.7: The typical short term stability of an output channel at 0V is shown here (BS series). Measurement device was a Fluke 8846A multimeter, 0.5sec. averaging per data point. One measurement point was taken every second.
In normal mode operation the command sent to [ACK-Symbol] the device is reflected (echoed) back. In fast mode operation the command sent to the device is not echoed back but only the acknowledge symbol (ASCII symbol 6) + CR www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884...

That means: a HV-series or BS-series device answers, serial number is 023, voltage range +/-5V, 16 channels, and having bipolar outputs. This identifier string is programmed into the FlashRom of every HV / BS series device by factory. The different string options are: first string part: always “HV”, also for BS devices...

Correction Command (advanced users only) The correction command is primarily used within the manufacturing process and adjusts correction routines inside the HV or BS series devices. The format of the correction command looks like “HV084 CORR02 0.12345 +0.54321”, which means that the device with serial number 084 is changed, specially channel number 2 in this case.
The product herewith complies with the requirements of the: 1. Low Voltage Directive 73/73EEC; 2. EMC Directive 89/336/EEC (including 93/68/EEC) and carries the CE Marking accordingly Date of Issue __________________ 15.
