RadioFans.CN 收音机爱 好者资料库 LOAD REACTANCE, PARAGRAPH 1-10D, add the following: There are two additional means of stabilizing the current loop operating with inductive loads: 1. Add capacitance in parallel with the output (inductive load). The value of capacitor can be from 0.1 uF to 1.0 uF depending on the value of the load inductance. 2. Add a series-connected resistor capacitor network in parallel with the output (inductive load). The value of resistor should be in the range of 100 to 500 Ohms and the value of capacitor should be 0.1 uF to 0.5 uF, depending on the load inductance value. The second option is recommended when the BOP is used only for DC operation or very low frequency output modulation into inductive loads. AFTER PAR. 3-3J) EXTERNAL LEADS add the following: K) EXTERNAL VOLTAGE MONITOR. Use signal Eo Monitor Output at pin 20 of the PC12 pro- gramming connector (see Figure 4-5) for external voltage monitoring. Caution should be exer- cised in handling this signal: use a series 5K resistor in combination with a high impedance monitoring device, or an external high impedance buffer between the BOP and the monitoring device. This signal is buffered by OPAMP IC23 (see Figure 6-4) which functions as a repeater for the signal coming from the RN3 matched pair divider connected at the output. There is no overvoltage protection. This stage is protected against short-circuit by the intrinsic protection of the OPAMP generating this signal. This signal is used by the BIT card if it is installed. L) EXTERNAL CURRENT MONITOR. Use signal Io Sensing Output at pin 10 of the PC12 pro- gramming connector (see Figure 4-5) for external current monitoring. This signal is not buff- ered. Use a series 5K resistor in combination with a high impedance monitoring device, or an external high impedance buffer between the BOP and the monitoring device. CAUTION: An accidental short-circuit at this terminal while the unit is in Current mode or Current limit mode will damage the BOP power stage. There is no overvoltage protection. This stage is protected against short-circuit by the intrinsic protection of the OPAMP generating this signal. This signal is used by the BIT card if it is installed.

World Wide Web: RadioFans.CN 收音机爱 好者资料库 DIGITAL CONTROL OF BOP POWER SUPPLIES, PARAGRAPH 3-46 add the following: The SN and SNR Programmers and the BIT 488 cards described in this manual are older meth- ods of controlling BOP power supplies via digital means. Although these products still function as described, the recommended method of digital control is now the use of Kepcos BIT 4886 16-bit plug-in card with resolution of 1/216. This plug-in card provides talk-listen support for the IEEE 488.2 bus using SCPI commands. The BIT 4886 card allows a BOP to communicate as a stand-alone instrument, directly on the GPIB. The BIT 4886 card also allows the BOP to be pro- grammed over the RS232C bus using either SCPI or CIIL commands via either an RS232-C terminal, or from a PC using a terminal emulation program with a baud rate of 9600, no parity, eight data bits and one stop bit. The downloadable BIT 4886 driver supports digital calibration (no manual pots) and multiple control and read-back ranges, For more information refer to: PERIODIC MAINTENANCE, PARAGRAPH 5-6, add the following: To clean the unit, proceed as follows: 1. Disconnect the unit from mains power. 2. Using a damp, lint-free cloth, wipe the exterior of the unit to remove accumulated dirt. 3. Reconnect AC power to the unit. RadioFans.CN 收音机爱 好者资料库
