R&S®HMP Series Application Examples Operating in Parallel and Serial Mode 5.2.1 Serial Mode Risk of electric shock due to exceeding low voltage protection For the series connection of all output voltages, it is possible to exceed the low voltage protection. In this case, any contact with live components is life-threatening. It is assumed that only qualified and trained personnel operate the power supplies and the connected loads. The following interconnection adds the individual output voltages.
R&S®HMP Series Application Examples Multi-Quadrant Operation Figure 5-3: Example of a parallel connection Generally, the channel with the highest output voltage provides the highest current. When this channel reaches the current limit, the channel connected in parallel supplies the remaining current. Note, that the voltages in the individual channels differ slightly due to tolerances. By increasing the voltage slightly, you can distribute the load more evenly.
R&S®HMP Series Application Examples Multi-Quadrant Operation reach a range between -32 V and +32 V. It does not refer to a negative display on the screen, but rather to a connection with an identical voltage range. However, a negative current (current sink) is not possible.

R&S®HMP Series Additional Basics on Remote Control Messages and Command Structure Annex A Additional Basics on Remote Control A.1 Messages and Command Structure A.1.1 Messages Instrument messages are employed in the same way for all interfaces, if not indicated otherwise in the description. See also: ● Structure and syntax of the instrument messages: Chapter A.1.
R&S®HMP Series Additional Basics on Remote Control Messages and Command Structure are device-specific, however, their syntax follows SCPI rules as permitted by the standard. Instrument responses Instrument responses (response messages and service requests) are messages which the instrument sends to the controller after a query. They can contain measurement results, instrument settings and information on the instrument status.
R&S®HMP Series Additional Basics on Remote Control Messages and Command Structure Syntax for Device-Specific Commands For demonstration purposes only, assume the existence of the following commands for this section: ● MEASure:CURRent[:DC]? ● MEASure:VOLTage[:DC]? ● FUSE[:STATe] {ON | OFF | 0 | 1} ● FUSE[:STATe]? Long and short form The mnemonics feature a long form and a short form. The short form is marked by uppercase letters, the long form corresponds to the complete word.

R&S®HMP Series Additional Basics on Remote Control Messages and Command Structure ● MINimum and MAXimum denote the minimum and maximum value. Example: VOLT:PROT? MAX Returns the maximum numeric value. Boolean parameters Boolean parameters represent two states: ● On (logically true), is represented by "On" or the numeric value "1" ● Off (logically false), is represented by "Off" or the numeric value "0" The instrument returns the numerical value when queried.
R&S®HMP Series Additional Basics on Remote Control Status Reporting System A.2 Command Sequence and Synchronization A sequential command finishes the execution before the next command is starting. To make sure that commands are actually carried out in a certain order, each command must be sent in a separate command line. As a rule, send commands and queries in different program messages. A.2.
R&S®HMP Series Additional Basics on Remote Control Status Reporting System A.3.1 Structure of a SCPI Status Register Each standard SCPI register consists of 2 or 3 parts (Event, Condition and Enable register). Each part has a width of 16 bits and has different functions. The individual bits are independent of each other, i.e. each hardware status is assigned a bit number which is valid for all 2 or 3 parts. Bit 15 (the most significant bit) is set to zero for all parts.
R&S®HMP Series Additional Basics on Remote Control Status Reporting System Bits 11 to 13 are still "free" resp. unused (always return a "0"). Certain areas of the registers are not used. The SCPI standard defines only the "basic functions". Some devices offer an advanced functionality. Each channel of the power supply is considered as separate "instrument" (SCPI standard definition). Therefore, e.g.
R&S®HMP Series Additional Basics on Remote Control Status Reporting System STATus:QUEStionable Register This register contains information about different states which can occur. It can be read using the commands STATus:QUEStionable:CONDition? and STATus:QUEStionable[:EVENt]?. See also Figure A-1. Table A-5: Bits of the STATus:QUEStionable register Bit No. Meaning 0 Voltage This bit is set while the instrument is in constant current mode (CC). The voltage is regulated and the current is constant.
