Page 167 4.4.2 Operational Principles • The 6253 contains a DA converter SrcDAC, for setting the voltage source or current source. It also has two DA converters, HiLimitDAC and LoLimitDAC for setting the current limits and voltage limit. The SrcDAC has 18-bit conversion accuracy, and the HiLimitDAC and LoLimitDAC have 16-bit conversion accuracy.
Page 168 6253 DC Voltage Current Source/Monitor Operation Manual 4.4.2 Operational Principles • Voltage range switching is done by A , and voltage measurement, voltage source, and voltage limit always take place in the same range. • The A and A amplifiers have high input impedance to minimize leakage.

The RS232 and LAN interfaces are also available as factory options. These interfaces cannot be used at the same time. Select which interface you wish to use.

Page 173 Overview GPIB (General Purpose Interface Bus) allows you to externally set the measurement functions and parameters on the 6253 and read out the measured data, making it simple to configure an automated measurement system. As GPIB signals from the 6253 are electrically isolated inside the unit from the measurement signal system, connecting external devices does not affect the measured values.

The TCP/IP communication is performed according to the following procedure: After turning ON, the 6253 waits for the computer sending a TCP/IP connection request with the specified port number (refer to Table 5-4.) The computer sends the TCP/IP connection request to the 6253.
Page 179 5.5.1 Overview RS-232 allows you to externally control the 6253 instead of operating the front panel (*). As RS-232 signals are electrically isolated from the measurement signal system, the measured values are not affected by noise or other factors of the external device.
