Electrical safety
If the information on electrical safety is not observed either at all to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.
1. Prior to switching on the product, always ensure that the nominal voltage setting on the product matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power fuse of the product may have to be changed accordingly.
2. In the case of products of safety class I with movable power cord and connector, operation is permitted only on sockets with an earthing contact and protective earth connection.
3. Intentionally breaking the protective earth connection either in the feed line or in the product itself is not permitted. Doing so can result in the danger of an electric shock from the product. If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use.
4. If the product does not have a power switch for disconnection from the AC supply network, the plug of the connecting cable is regarded as the disconnecting device. In such cases, always ensure that the power plug is easily reachable and accessible at all times (corresponding to the length of connecting cable, approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from the AC supply network. If products without power switches are integrated into racks or systems, a disconnecting device must be provided at the system level.
5. Never use the product if the power cable is damaged. Check the power cable on a regular basis to ensure that it is in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, you can ensure that the cable will not be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock.
6. The product may be operated only from TN/TT supply networks fused with max. 16 A (higher fuse only after consulting with the Rohde & Schwarz group of companies).
7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket. Otherwise, sparks that result in fire and/or injuries may occur.
8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric shocks.
9. For measurements in circuits with voltages V rms
> 30 V, suitable measures (e.g. appropriate measuring equipment, fusing, current limiting, electrical separation, insulation) should be taken to avoid any hazards.
10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply in each case.
11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the product.
12. If a product is to be permanently installed, the connection between the PE terminal on site and the product's PE conductor must be made first before any other connection is made. The product may be installed and connected only by a licensed electrician.
13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fused in such a way that anyone who has access to the product, as well as the product itself, is adequately protected from injury or damage.
1171.0000.42-05.00 Page 3

1.2 Description of product
The Power Supply/Load Module R&S TS-PSU is a module based on
CompactPCI developed for use on the ROHDE & SCHWARZ R&S
CompactTSVP and R&S PowerTSVP production platform. It has a width of only one slot and a height of four units. It has two floating Channels that are completely independent of each other with a maximum power of 50 W each, a voltage range of +/-50 V and a maximum current of 3 A. The currents and voltages can be programmed in both the positive and negative range. Thanks to this 4-quadrant capability of the module, it can also be operated in applications as a load (sink).
The measurement units integrated into the module for each channel make it possible to read back the current and voltage of any given channel. Using the multiplexer included in the module, it is also possible with the R&S TS-PSU to measure external voltages over time directly on the test object. The functionality of the module also includes extensive options for controlling individual channels via trigger lines and generating trigger signals. As with all modules available from
ROHDE & SCHWARZ, the R&S TS-PSU also has access to existing analog measurement buses in the R&S CompactTSVP and R&S PowerTSVP with both channels. This measurement bus makes it possible to switch outputs without any extra wiring to other measurement and switching cards present in the R&S CompactTSVP / R&S PowerTSVP.

Function Description Power Supply/Load Module R&S TS-PSU
5.2 Power supply/load unit
The Power Supply/Load Module R&S TS-PSU is designed as a 4quadrant source consisting of a 2-quadrant output stage followed by a polarity switch. The output stage consists of a linear regulator with current and voltage feedback. The linear regulator receives its power through the PSU-AC/DC converter.
The settings for output voltage and maximum current are used to configure the output stage. Users can select between two voltage and three current ranges.
The following voltage ranges are available:
• 50 V
• 15 V
The following current ranges are available:
• 10 mA
• 100 mA
• 3 A
For a summary of the possible combinations of voltages and currents,
see the characteristic diagram in Section 5.2.1.
The setting of current and voltage range determines the resolution of the module. Because of this, the smallest possible range appropriate for any given application should be used. The resolution of voltage setting is 16 bits plus a positive/negative sign. For current, 16 bits represent the quantity only; no positive or negative sign can be selected.
Below the maximum current set, the output stage works as a constant voltage source, otherwise as a constant current source, or switches off
(depending on the configuration). Please also refer to Section 5.2.11,
item 5.
Switching between source mode (Source) and load mode (Sink) is done automatically.
In sink mode, current is also regulated. In addition, the voltage is programmed to less than the externally applied voltage, to force current flow from the test object to the R&S TS-PSU. This may increase the voltage at the output to rise to the level of the external source, but not beyond the range (15 V, 50 V).
Over-Voltage-Protection (OVP) should be adjusted appropriately to protect the output stage, especially if the voltage of the external source is higher than the range.
5-2
Power Supply/Load Module R&S TS-PSU Function Description
Behaviour when the maximum current is exceeded can be defined by calling function rspsu_Attr_Current_Limit_Behaviour().
When „Regulate“ (basic state) is selected, the output current is limited; with “Trip” the output is turned off.
Example of sink operation:
Purpose: Discharging an accumulator with an output voltage of 8 V to
6 V with a maximum discharge current of 1 A. The internal resistance of the accumulator is 1
.
Setting R&S TS-PSU: U = 6 V, I = 1 A
The charged accumulator with U = 8 V is connected to the
R&S TS-PSU. The R&S TS-PSU controls discharging of the accumulator based on the specified setting so that the current flows at a maximum of I = 1 A. Thus with an internal resistance of 1
and a maximum current of 1 A, the voltage difference between the output voltage of the
R&S TS-PSU and the voltage of the accumulator must not exceed 1 V.
It follows that at the beginning of discharge on the output of the
R&S TS-PSU, a voltage of 7 V is present, which slowly drops to a value of 6 V as the accumulator discharges. Once the voltage of the
R&S TS-PSU has reached 6 V, that value is maintained. As soon as the accumulator voltage has also fallen to 6 V, no more current will flow and discharging is complete.
5.2.1 Characteristic diagram
The maximum voltage or current values are determined by the characteristic data of the R&S TS-PSU. In addition to the absolute limits 50 V and 3 A, a maximum output power (CURRENT_LIMIT *
VOLTAGE_LEVEL) of 50 W must not be exceeded in source operation and 20 W in sink mode (continuous operation). This results in the char-
acteristic diagram for Source and Sink mode shown here (Figure 5-2).
Special cases must be taken into consideration for low voltages.

5.2.2 Reverse polarity in load case
If an external source is connected to the R&S TS-PSU that has the opposite polarity to the output voltage set, the R&S TS-PSU will attempt to impose the polarity set by the user. This must not cause the maximum current set to be exceeded, however. External behaviour depends on the external source and its ability to provide current.
5-4
Power Supply/Load Module R&S TS-PSU Function Description
5.2.2.1 Weak external source (current remains below the maximum current)
When weak external sources are connected, the R&S TS-PSU forces the polarity set on its pins.
CAUTION!
This reverses the polarity of the external source, which could be damaged under some circumstances!
5.2.2.2 Strong external source (able to provide a high current)
When a strong external source is connected, the R&S TS-PSU detects this and remains in the externally applied quadrant, even though according to specification it should be working in a different quadrant. The
R&S TS-PSU sinks the maximum current set. After discharge (voltage on the pins is approximately < 0.8 V) of the external source, the
R&S TS-PSU switches to the desired polarity and from then on changes the external source with reverse polarity.
CAUTION!
This reverses the polarity of the external source, which could be damaged under some circumstances!
5.2.3 Inductive loads
Turning off inductive loads suddenly can generate very high voltage spikes. Freewheeling diodes should therefore be used to protect the output stage of the R&S TS-PSU.
If it is not possible to use freewheeling diodes, proceed as follows when switching off inductive loads:
1.
Set the output voltage = 0 V
2.
Wait until the current drops to close to 0 A
3.
Turn off R&S TS-PSU electronically
4.
Open the relay(s)

Function Description Power Supply/Load Module R&S TS-PSU
5.2.4 External sensing
To compensate for voltage drops in the line to the external load or source, the R&S TS-PSU can be set to external sensing. Then two additional lines directly to the test object are required. The measured voltage difference on these lines is automatically regulated to the target voltage by the R&S TS-PSU.
If the R&S TS-PSU is operated with external sensing, the sense lines must be connected to corresponding input pins on the front connector and switched through the relay matrix to the sense inputs. Otherwise an incorrect voltage will be assumed for regulation of the output voltage, causing an incorrect output voltage to be generated. For reasons of safety, however, the error voltage of the output stage is limited to a difference of approximately 4 - 5 V. This limit also applies if the sense lines are accidentally shorted or connected with reverse polarity. This determines a maximum correctable error voltage based on maximum line resistances of 4 - 5 V.
Since the pins for external sensing are also used for external voltage measurement, no additional external voltage can be measured in "external sensing" mode.
5.2.5 Current limiting when using matrix relays in the output path
Reed relays are used as matrix relays (see Section 5.4.1) in the
R&S TS-PSU with a current load capacity of 1 A. Because of this, when a matrix relay from the output path to the analog bus is closed by the software, automatically a current limit of 1 A is turned on. If current limiting was previously set to a lower value, the lower value will be used.
This function can be disabled. In this case, the relays will remained unprotected.
Default setting: „Function enabled“
5-6
Power Supply/Load Module R&S TS-PSU Function Description
NOTE:
This protective mechanism is subject to some restrictions. Since current regulation involves a certain delay, peak currents that could cause damage to the relay contacts may nevertheless occur. To prevent such damage, the relay contacts should normally be switched to a no-current state. For this the R&S TS-PSU offers a command to switch (inhibit) outputs on and off electronically by software.
5.2.6 Power dissipation and settling time
The linear controller in the PSU power module is supplied with power by an external PSU-AC/DC converter. To perform the controlling functions correctly, the linear controller always requires a supply voltage that is at least approx. 5 V above the respective output voltage.
To check the output voltage of the PSU-AC/DC converter, the user has three different options:
• Mode 1 : automatic preselection through the firmware
• Mode 2 : Control via the PSU output voltage
• Mode 3 : Manual setting via the internal D/A converter
In Mode 1 (“automatic preselection through the firmware”), the firmware selects mode 2 or mode 3 as the optimum operating mode, depending on the current setting. Basically, at a current setting below 400 mA
(50 V range) or 1.3 A (15 V range), the PSU-AC/DC converter voltage is set to a fixed value (55 V or 20 V), since the maximum dissipation loss cannot be exceeded in this case (Mode 3) . In all the other cases, the PSU-AC/DC converter voltage is controlled through the PSU output voltage (Mode 2).
Mode 2 (“control via the PSU output voltage”) ensures that the output stage is always supplied with the minimum voltage required, which keeps the dissipation loss to a minimum too. A disadvantage is that the settling time may be considerably higher with an increase in the nominal output voltage, since the setting speed of the PSU-AC/DC converter output voltage is limited. Approx. 3.5 A are available for the rising edge, which - apart from the output voltage - also have to charge the capacities in the PSU-AC/DC converter and in the PSU power module.
In Mode 3 (“manual setting via D/A converter”), an increase in the PSU output voltage can be achieved at a maximum speed within the range
5-7
Function Description Power Supply/Load Module R&S TS-PSU
of from 0 V up to the set supply voltage of - 5 V. Excessively high supply voltage in combination with high current values results in high dissipation loss of the output stage and thus, after a certain delay, in thermal cut-out. The static dissipation loss limit is at approx. 22 W, i.e. at
3 A at approx. 7 V of overvoltage.
As a rule, the PSU-AC/DC converter output voltate is aways increased at the maximum possible speed. The speed is limited only by the available re-charging current (approx. 3.5 A) and the given capacities on the
PSU-AC/DC converter and the PSU power module (together approx.
300 µF).
A decrease in the PSU-AC/DC converter output voltage is effected at different speeds depending on the respective power consumption (the more power, the faster). The time constant without any current flow is approx. 100 ms.
5.2.7 Wiring channels in series (cascading)
Serial wiring of the two output channels of the R&S TS-PSU is possible using external wiring. To do this, current limiting of the two channels should be set to approximately the same value (difference about 1% of range). We urgently recommend that you remain in constant volt-
age mode. Otherwise the module may be destroyed at high cur-
rents. If the current exceeds the value set, one channel will first regulate the voltage to a lower value; the second channel will follow somewhat later. The difference is determined by the amplification and offset error of the current regulator.
CAUTION!
Each separate GND relay must be set specifically! Both GND relays must never be closed together. Doing so would cause a internal short circuit.
WARNING!
Connecting the outputs of the channels in series (cascading) makes it possible to generate voltages dangerous to the touch of up to 100 V!
Floating channels must never exceed a voltage of 125 V against ground. This applies to each individual connection pin. It is especially important to observe this requirement when both sources are cascaded, for example when they are switched together in the adapter. For

more information, see Section 6.5.
5.2.8 Connecting channels in parallel
The R&S TS-PSU is not designed for parallel wiring of outputs and the possible resulting currents of up to 6 A . Because of this, the outputs must not be wired in parallel. Because of the 4-quadrant capability, equalisation currents could flow between the two channels (with one source working in source mode, the other in sink mode).
5.2.9 Electronic on/off and PWM
The R&S TS-PSU has an electronic switch for rapid On / Off switching of the output path. For reasons of safety, the module is automatically switched to “Off” after initialisation.
The R&S TS-PSU also offers an option for quickly switching back and forth between 0 V and the programmed value with the pulse width modulator (PWM) integrated into the module. This makes it possible, depending on the voltage setting, to generate pulses with a width of at least 50 µs and a maximum frequency of approximately 10 kHz.
5-9
Function Description Power Supply/Load Module R&S TS-PSU
5.2.10 Dynamic Operation
Dynamic opeation refers to the operation with changing current and/or voltage. It can be achieved as follows:
• Frequent and rapid (<100 ms) reprogramming of the voltage and/or current setting
• Frequent and rapid change of the polarity
• Frequent and rapid change of the load
• PWM Operation
• Output of an “arbitrary waveform”
• Triggered output with frequent and rapid programming of a new voltage and/or current value
• “gated” Operation
With dynamic operation, the descriptions in Section 5.2.6 must be
heeded by all means with respect to settling time and dissipation loss.
Especially with high currents (above 400 mA in the 50 V range, 1.3 A in the 15 V range), the setting of the supply voltage of the output stage is important.
As a rule, this supply voltage cannot be set at any desired speed. Thus, if this voltage is controlled via the mode “Control via the PSU output voltage”, the maximum dissipation loss may still be exceeded, sine the supply voltage decreases gradually on the trailing edge of the PSU output voltage, which results in the maximum dissipation loss being exceeded.
An example in this context: Output short-circuited or loded with low resistance, switched on, current = 0 A, voltage does not matter (e.g. 5 V).
With Mode1 (“automatic preselection through the firmware”), the PSU supply voltage is set to 55 V. If the current limit is now set to 3 A, the firmware will switch to “Control via the PSU output voltage”. Since the output voltage is almost 0, the voltage of the PSU-AC/DC converter is reduced, which, however, takes some time. At first, up to a noticeable reduction, the output stage must process up to 3 A x 55 V = 165 W, which results in thermal cut-out with an already heated output stage
(due to any previous currents).

Power Supply/Load Module R&S TS-PSU Function Description
5.2.11 Protective mechanisms
A series of protective mechanisms are integrated into the output stage to prevent damage to the R&S TS-PSU and externally connected devices. When necessary, these protective mechanisms turn off the linear regulator of the appropriate channel and open the relays of the force lines. The LEDs assigned to the channel (CH1 or CH2) begin to flash.
The channel cannot be connected and activated again until the user has confirmed that the protective mechanism has engaged. Driver function rspsu_ResetOutputProtection is used for this purpose.
It can also be implicitly called by resetting the module (rspsu_reset).
The module software can also be used to query whether a channel is in voltage or current mode, and whether a protective mechanism has been triggered.
1.
Over-voltage protection
If the voltage at the force pins exceeds the programmed threshold value, the protective mechanism will respond. To ensure effective operation, the value must be far enough above normal operation so that minor deviations do not cause triggering.
2.
Current monitoring
High currents may flow if regulation fails or in the event of overload. To prevent damage, overcurrent protection engages at approximately 120 % of the current range. Example: With a the current range of 3 A, overcurent protection engages at 3.6 A.
3.
Excess temperature protection
Several temperature sensors are built into the R&S TS-PSU to protect the linear regulator. One of these temperature sensors continuously monitors the temperature on the heat sink of the PSU power module. If the limit value of 70°C is exceeded, the protective mechanism for the linear regulator engages. In some applications, however, (for example PWM mode at high frequency and high current), it is possible that only the linear controller will heat up very quickly, without the temperature of the heat sink coming close to the limit temperature of 70°C. A temperature sensor integrated into the linear controller monitors its temperature in addition and switches off the linear controller when necessary to prevent it from being destroyed by excess heat. This condition is also detected by the R&S TS-PSU and results in the affected channel being turned off.
5-11
Function Description Power Supply/Load Module R&S TS-PSU
4.
Monitoring power supply voltages
If one of the power supply voltages is not correctly applied (for example PSU AC/DC converter not turned on), this will cause the protective mechanism to engage and the yellow LED for that channel will begin to flash.
5.
Current limiting
The behaviour of the current limiting function can be configured.
With the “regulate” setting, the set current is controlled (default), with the “trip” setting, the system is switched off in the case of a current flow above the set current value.

Power Supply/Load Module R&S TS-PSU Function Description
5.3 Measurement unit
The integrated measurement unit of the Power Supply/Load Module
R&S TS-PSU consist of 16-bit ADC with a sampling rate of 10 kHz and a front end multiplexer for selecting different sources or measurement points. The measurement unit is closely connected to the output stage of the associated channel and works on the same internal measurement reference point.
5.3.1 Measurement options, resolution
The R&S TS-PSU offers the following measurement options:
1.
Measurement of output voltage on the force pins
2.
Measurement of voltage on the sense pins
3.
Measurement of currents via internal shunt
When the output stage is switched to “internal sense” mode, any external voltage can be measured on the sense pins. Without additional wiring only differential measurement is possible, since the R&S TS-PSU cannot switch an internal ground connection to CHx_SHI or CHx_SLO.
Due to an external wiring from CHx_LO to CHx_SLO and closing of the ground relay, “single ended” measurement is also feasible. The difference in voltage may be up to
50 V. The maximum voltage of each individual signal must not exceed
50 V against CHx_LO.
The voltage measurement range (measurement option 1 and 2) is always
50 V.
The current measurement range (measurement option 3) is specified by the setting of the R&S TS-PSU. For example, if the range is set to
10 mA, the range of the measurement unit will also be
10 mA.
5.3.2 Sampling
The measurement unit implemented on the R&S TS-PSU makes it possible to record individual values, average values, or entire diagrams. To record transient processes or current and voltage values over time, the
R&S TS-PSU is able to record the selected source at a sampling rate of up to 10 kHz and save measurement values. The available memory depth is designed for up to 10000 measurement values. The sampling rate, duration of recording, start delay, and triggering can be freely selected. At the maximum sampling frequency, an interval of one second can still be measured. Correspondingly longer recording is possible at lower sampling frequencies. The measurement can be started via inter-
5-13
Function Description Power Supply/Load Module R&S TS-PSU
nal or external triggers. It is also possible to start the measurement in the background and retrieve the measurement values later.
5.3.3 Monitor output
The R&S TS-PSU has two pins on the X10 front connector that pass the input voltage of the ADC to the output through a buffer. In this way, the selected measurement source can be recorded using an external oscilloscope or digitizer. The voltages and value range on these monitor outputs (CHx_MHI and CHx_MLO) are as follow:
Selected source

Source current in mA = 5.02 * monitor voltage in V
Source current in mA = 48.1 * monitor voltage in V
Source current in A = 1.49 * monitor voltage in V
The monitor output signal must be measured differentially at high impedance. 10 k
is built in internally before CHx_MHI and CHx_MLO each as a protective mechanism against short-circuits.
CAUTION!
Signals CHx_MHI / CHx_MLO must be measured floating against the force or sense potential. Depending on the quadrant of the source, the potential against CHx_MLO approximates CHx_LO
(output voltage positive) or CHx_HI (output voltage negative).
This means the common mode voltage on CHx_MLO against
CHx_LO is approximately 0 V to approximately -50 V.

5.4.1 Matrix and front relay
The front lines can be switched via the front relays (currents up to 3 A) to four outputs on the front connector.
The Pins on the front connector are designed for a current load of max.
1 A per pin, i.e. with higher currents, several pins must be used to prevent that the plug-type connector is destroyed due to overload.
Four sense or measurement imputs (two-pin) can also be directed via the sense lines with a maximum current of 1 A to the source or measurement unit.
All lines have access to the local analog bus through the matrix relay and via the coupling relay to the analog bus in the R&S CompactTSVP.
All matrix relays and coupling relays can switch a maximum of 1 A. For safety reasons, current limiting is automatically reduced to 1 A when a matrix relay is in use, although this mechanism offers only limited, ad-
ditional protection (see Section 5.2.5).
To prevent the relay contacts from being destroyed, the relays should only be switched if no current is flowing through them. Before a contact is activated, the channel should be turned off electronically.
The following function should be available to operate these relays:
– rspsu_Connect
– rspsu_Disconnect
– rspsu_DisconnectAll
The function rspsu_DisconnectAll can be used to break all connections that were set up with rspsu_Connect with a function call. rspsu_DisconnectAll has no effect on the configuration of the coupling relay or ground relay.
5.4.2 Coupling Relay
The coupling relays connect the local analog bus on the module with the analog bus in the R&S CompactTSVP. The function rspsu_ConfigureCoupling defines the status of the coupling relays. Please consider that the function rspsu_DisconnectAll does not open these relays.

Power Supply/Load Module R&S TS-PSU Function Description
5.4.3 Ground relay
Each channel of the R&S TS-PSU has its own ground relay that can be used to connect the CHx_LO signal to ground. PSU channels are operated ground free in their basic state. The function rspsu_ConfigureGround is used to determine whether a channel is being operated with ground reference or ground free. Also note that rspsu_DisconnectAll does not affect the ground relay!
NOTE:
For technical reasons, a non-switched PSU channel (all matrix and front relays of a channel are opened) is automatically grounded with the ground relay. It is automatically opened again before another connection is made if the channel is configured ground-free.

Power Supply/Load Module R&S TS-PSU
5.5.1 Trigger outputs
The Power Supply/Load Module R&S TS-PSU can generate trigger signals on lines PXI_TRIGn (X20) and XTOn (X10). The polarity of the trigger signal can be adjusted. The following events may cause a change in the level on trigger lines:
• Call to function rspsu_InitiateTrigger. This function generates a “General Purpose” trigger (trigger pulse approximately 1 µs long) if trigger source “GP” has been configured to one or more trigger outputs by rspsu_ConfigureTriggerOutput.
• Switching a channel on or off if trigger source “CH1” or “CH2” has been configured to one or more trigger outputs by rspsu_ConfigureTriggerOutput.
5.5.2 Trigger inputs
Trigger signals on trigger inputs PXI_TRIGn (X20) and XTIn (X10) can start a measurement value recording (voltage or current) in the measurement unit or set the output voltage and current limiting of the source to a new value. The two channels can be triggered synchronously.

Power Supply/Load Module R&S TS-PSU
5.6 Operation as electronic load
Function Description
5.6.1 General
The following additional modes are available to operate the
Power Supply/Load Module R&S TS-PSU as an electronic load:
• Operation as constant current sink (Constant Current Mode)
• Operation as a resistance load (Constant Resistance Mode)
• Operation as a load with constant power (Constant Power Mode)
In these modes, the device software uses both the supply / load unit and the measurement unit to control the electronic load. Therefore, the measurement unit cannot be used by the operator in these modes. In these modes, the applied voltage and the current flowing are continuously measured by the measurement unit and evaluated by the device software depending on the selected mode. The modes can be activated using the rspsu_ConfigureMode function.
In the constant current mode, the measured voltage is used to monitor the polarity of the connected source. The measured current is compared with the reference value. If it lies within the tolerance range, the status „Regulated“ is indicated.
In the resistance load and constant power load modes, the input voltage is continuously measured and the new value for limiting the current is calculated and set. When the applied voltage is stable and thus current limitation is correctly set, a current measurement is performed. If the measured value lies within the expected tolerance range, regulation is engaged and the „Regulated“ status bit is set.
The measuring rate and the adjustment speed of the R&S TS-PSU are limited. In the worst case, the time for adjusting the current is 12.8 ms.
For the current to be adjusted, the applied voltage must be stable. The load modes cannot therefore be used for AC voltages.
Inductance in series to the load can impair the stability of the regulation.
It counteracts the change in the current: dU = -L * di / dt.
A current increase of 1 A / µs with an inductance of 1 µH creates a voltage drop of 1 V.
To counteract voltage drops, the regulation algorithm limits the current increase to 100 mA / 400 µs. In addition, the integral component of the
PI algorithm counters voltage fluctuations. This stabilises the regula-
5-19
Function Description Power Supply/Load Module R&S TS-PSU
tion.
Other measures to prevent oscillating regulation include:
• Connecting a capacitor parallel to the output to stabilise the voltage.
• Choosing the largest possible wire cross-section to connect the load.
• Using the shortest possible wires.
• Keeping the space between the outward and return wires to a minimum (twisted wires are the optimum solution).
The current regulation status can be queried using the rspsu_QuerySinkState driver function. As well as a status register, this function also returns the measured voltage and current values. As the measurement unit cannot record current and voltage simultaneously and only with a delay, two bits in the status register indicate the validity of the other return values. If the return values are invalid, the value
IVI_VAL_NAN is returned for current and/or voltage.
The following bits are defined in the status register:
Symbolic name
RSPSU_SS_VOLT_VALID
Value Meaning
0x0001 This bit is set if a valid voltage value is present. The associated „OVR“ bit (over range) is then also valid. After turning on the R&S TS-PSU in the load modes, it takes some time until the first measurement result is available.
RSPSU_SS_CURR_VALID 0x0002 This bit is set if a valid current value is present. The associated „OVR“ bit (over range) is then also valid. After turning on the load, it takes some time until the first measurement result is available. The current measurement is only performed if the measured voltage is stable. Each time a change in voltage is measured, this bit is initially reset and current measurement interrupted.
Table 5-2 Bits in status register for load simulation
5-20
Power Supply/Load Module R&S TS-PSU Function Description
Symbolic name
RSPSU_SS_REGULATED
RSPSU_SS_VOLT_OVR
Value Meaning
0x0004 This bit is set if the current flowing into the
R&S TS-PSU module and measured using the measurement unit lies within a tolerance range around the reference value.
The following tolerances are used:
10 mA range ± 134 µA
100 mA range ± 1.3 mA
3 A range ± 40 mA
The applied voltage must be stable for the current measurement to be performed. This bit is reset when the input voltage changes.
0x0010 This bit is set if the measured voltage is outside the set range. In this case, IVI_VAL_NAN is returned for the measured value and the R&S TS-PSU is shut down. The shutdown must be acknowledged by the operator before the channel can be used
again. Refer to chapter 5.2.11: Protective mechanisms.
RSPSU_SS_CURR_OVR 0x0020 This bit is set if the measured current is outside the set range. In this case, IVI_VAL_NAN is returned for the measured value.

NOTE:
The other bits in the status register are used for internal purposes and can thus have different values.

5.6.2 Operation as constant current sink
Examples of the use of this mode include discharging batteries or determining the capacity of a battery. A constant current is drawn from the connected source until the set output voltage (final discharging voltage) is reached. This mode differs from „Normal“ mode in that the polarity of the R&S TS-PSU is automatically adjusted to the connected source. To do this, the voltage is measured using the measurement unit and the load unit is reconfigured if required (reverse polarity protection). Refer
to chapter 5.2.2: Reverse polarity in load case.
This mode is configured using the rspsu_ConfigureConstCurrent function. This is used to set the current to be drawn and the output voltage of the R&S TS-PSU. To achieve high accuracy, an appropriate range should be selected for the voltage and current.
CAUTION!
The externally applied voltage may not exceed the upper limit of the range. The over voltage protection should be adjusted appro-
priately to protect the limit. Refer to 5.2: Power supply/load unit.
5.6.3 Operation as resistance load
The main characteristic of this mode is that the load current depends on the applied voltage in line with Ohm's Law. An electronic resistance load is used to load external sources with a constant resistance. Practical applications include:
• Power pack test
• Battery test
• Testing microprocessor voltage regulation circuits
The applied voltage is continuously measured by the device software and the current limitation is adjusted depending on the programmed resistance value. The R&S TS-PSU output voltage is set to 0 V. When the applied external voltage has a stable value, regulation is verified using the current measurement.
The rspsu_ConfigureConstResistance function can be used to set the required resistance value. The value that can be reached depends on the selected ranges. The following table shows the range limits.

Note that the maximum resistance can only be reached if the applied voltage is sufficiently high. The higher voltage guarantees that a current is flowing that can be regulated by the R&S TS-PSU. However, the externally applied voltage may not exceed the upper limit of the range.
The over voltage protection should be adjusted appropriately to protect
the limit. Refer to chapter 5.2. The minimum resistance is only reached
if the voltage is low enough to ensure that the current limitation range is not exceeded. For regulation to continue functioning correctly, the voltage may not be lower than 0.5 V.
5-23
Function Description Power Supply/Load Module R&S TS-PSU
5.6.4 Operation as load with constant power
The main characteristic of this mode is that the load current depends on the applied voltage and a set power. Therefore, an external source is loaded with a constant power.
In this mode, the voltage is also measured by the device software and the current limitation is adjusted accordingly. The R&S TS-PSU output voltage is set to 0 V.
The rspsu_ConfigureConstPower function can be used to set the required power. The value that can be reached depends on the selected ranges. The following table shows the range limits.

Note that the minimum power can only be reached if the applied voltage is sufficiently low. However, the voltage may not be lower than 0.5 V.
At voltages of less than 0.1 V, the current limitation is always set to the lowest possible value in the currently selected range. The maximum power is then only reached if the voltage is sufficiently high. This means that the maximum current in the range is not exceeded. The externally applied voltage may not exceed the upper limit of the voltage range.
The over voltage protection should be adjusted appropriately to protect
the limit. Refer to chapter 5.2.
NOTE:
For voltage jumps at the electronic load input or when turning on, when regulating the current the external source can be temporarily loaded with higher currents than in the regulated state.
If the voltage from the source then drops, the requirement for constant power regulates the current limitation to a higher value.
If the external source cannot supply this current and the voltage falls further, an unexpected operating point occurs. In this case, it makes sense to initially apply a lower load to the source.

Power Supply/Load Module R&S TS-PSU Function Description
5.6.5 Regulation accuracy
The regulation accuracy in „Constant Resistance“ and „Constant Power“ mode depends on the voltage measurement accuracy and the accuracy of the adjustable current for current limitation.
The data sheet includes the following accuracies:
Voltage measurement accuracy:
• ± (0.1% + 50 mV)
Current regulation accuracy:
•
•
• in 10 mA range: in 100 mA range: in 3 A range:
± (0,4% + 20 µA)
±(0,4% + 200 µA)
±(0,4% + 6 mA)
The regulation accuracy can be calculated as follows:
The input voltage is used to calculate the minimum / maximum measured voltage:
Umin = U - (U * 0,1% + 50 mV)
Umax = U + (U * 0,1% + 50 mV)
The minimum / maximum measured voltage can be used to to calculate the minimum / maximum target current:
In „Constant Resistance“ mode:
Inom,min = Umin / Rnom
Inom,max = Umax / Rnom
In „Constant Power“ mode:
Inom,min = Pnom / Umax
Inom,max = Pnom / Umin
By specifying the current accuracy of the source, Inom, min and Inom, max can be used to calculate the minimum / maximum value of the set current limitation.
For example, for the 3 A current range:
Imin = Inom,min - (Inom,min * 0.4% + 6 mA)
Imax = Inom,max + (Inom,max * 0.4% + 6 mA)
The minimum current limitation value lmin, the maximum current limitation value lmax and the input voltage can be used to calculate the min-

imum resistance Rmin, the maximum resistance Rmax, the minimum power Pmin and the maximum power Pmax.
Rmin = U / Imax
Rmax = U / Imin
Pmin = U * Imin
Pmax = U * Imax

6.5 Safety instructions
6.5.1 General
WARNING!
The R&S CompactTSVP/ R&S PowerTSVP production platform and the Power Supply/Load Module R&S TS-PSU are designed so that users can operate at volatages up to 125 V. The requirements according to EN61010-1 for operation with “hazardous live” voltages must be observed.
CAUTION!
If signals with voltages dangerous to the touch are being transferred via the analog bus, all modules involved, including PXI-external modules, must be specified for the relevant voltage.
6.5.2 Replacing the R&S TS-PSU
WARNING!
Before replacing the R&S TS-PSU, the R&S CompactTSVP/ R&S
PowerTSVP must always be turned off or the power plug must be disconnected. All connections to external test objects must be disconnected.
WARNING!
Before the PSU power module is removed from the R&S CompactTSVP / R&S PowerTSVP housing, make certain the module has had sufficient time to cool off. The cooling body of the PSU power module may heat up during operation under full load, etc..
In order to avoid possible injury (for example burns) to the user, the PSU power module should be cooled off before it is removed.
The cooling-off process can be sped up if the PSU AC/DC converter is turned off or the output stage is disconnected via the relay while the R&S CompactTSVP / R&S PowerTSVP and its fans continue to run.

6.5.3 Instructions for operation with voltages dangerous to the touch
In conformity with EN 61010-1, the following voltage limit values are considered „Hazardous live“.
• 70 V DC
• 33 V AC eff
• 46.7 V AC peak
WARNING!
When operating the Power Supply/Load Module R&S TS-PSU above these voltage limit values, the requirements of EN61010-1 must be observed.
The Power Supply/Load Module R&S TS-PSU and Test System
Versatile Platform R&S CompactTSVP / R&S PowerTSVP are designed for a maximum voltage of 125 V between ground-free measurement devices, analog buses, and GND. Care must be taken to ensure that this limit is not exceeded at any time, even as the sum of voltages, and thus not as a results of alternating signals.

Power Supply/Load Module R&S TS-PSU Self-Test
8.3 TSVP self-test
As part of the TSVP self test, an extensive test of the R&S TS-PSU module is performed and an exhaustive protocol is generated. This is done with the “Self-Test Support Library”.
The R&S TS-PSAM analog stimulus and measurement module is used as a measurement unit in the TSVP self-test. The functionality of the modules in the system is ensured by measurements via the analog bus.
First the global analog bus and then the local analog bus are tested for valid voltages. These voltages could possibly come from an outside source, for example through sources that are connected. After an isolation measurement between the buses, all the relays (coupling, matrix, multiplexer, sense relays) are tested. The voltage and current measurements of the sources and PSU-AC/DC converter are made. The voltage and current section are tested for the measurement unit. Finally triggering via PXI lines is tested.
NOTE:
You can find information about starting the self-test and the order of required work steps as well as a detailed description of parameters and sequences that are tested in the R&S CompactTSVP / R&S Power TSVP Service Manual.

CHA_GND
The CHA_GND signal is connected with the front plate of the module and via two 10 nF capacitors with GND. The front plate itself has no direct connection to GND. When a test object is connected, the test object GND should be connected to GND. To avoid ripple loops, do not connect GND and CHA_GND.
