6. Specications
5. Unpacking
5.2 Damage Inspection
6.1 Specication Conditions
Examine the components for evidence of shipping damage. If damage has occurred, please contact Ossila
directly for further action. The shipping packaging will come with a shock indicator to show if there has been
any mishandling of the package during transportation.
The specications and information in this document are for the Ossila Source Measure Unit. All units meet
these standard specications when dispatched to the end-user.
The accuracy of both source and measurement of the unit are specied under the following conditions:
• Ambient temperature of 23 °C ± 5 °C, < 60% relative humidity.
• After a 30-minute warm-up period.
• Default measurement speed (OSR 5) unless specied.
• No lter.

11
6.2 Source Measure Units (SMU 1 and SMU 2)
The source measure units output a voltage and then measure both the voltage and current. The output
voltage is always measured at the output of the BNC (rather than assuming it is at the set voltage) in case of
any load eects (for example short circuiting the output or low impedances causing a small drop in voltage).
Each source measure unit has manually selectable ranges so that both high and low currents can be
measured accurately.
6.2.1 Power Specications
The unit is specied for a maximum operation power as in Table 6.1. Figure 6.1 shows the four-quadrant
safe operation zone of the unit.

9x1 32768 200 nV 2.2 3
There is some allowance for being beyond these limits (± 10 V and ±200 mA). The unit has internal voltage
and current limits set at ±10.5 V and ±225 mA. If a voltage or current greater than these values is measured
on either SMU, the red error LED next to the SMU will turn on and the output voltage of the SMU will be set
to 0 V. This is a measure to reduce the possibility of damaging the unit due to excessive voltages or currents.
The voltage and current limits can be changed programmatically, but they should not be increased past the
default values as this will increase the possibility of damaging the unit.
6.2.2 Measurement Speed
The Ossila Source Measure Unit utilises a high-speed, 24-bit no Latency ∆Σ™ ADC. It provides ten speed/
resolution combinations (6.9 Hz/200 nV RMS noise to 3.5 kHz/25 µV RMS noise) which can be selected,
with no latency between conversion results. Additionally, a double-speed mode can be selected, enabling
output rates up to 7 kHz with one cycle latency. These modes are linked to a single variable called OSR
(Oversampling Rate) which is used to program the unit and take the measurement. Table 6.2 lists the various
speed settings of the unit, with maximum measurement rates for both SMU and voltmeter channels.

6.2.3 Voltage Source and Measurement Specications
Warning: Do NOT attach external voltage sources to either SMU module as this may result in
damage to the unit.
6.2.4 Current Measurement Specications
The current measurement of the Ossila Source Measure Unit is spread over 5 ranges. Each range has
a dierent maximum current, accuracy, and resolution. As the range number increases, the maximum
measurable current decreases, but the accuracy and resolution increase.
Table 6.4. Current measurement specications.

6.3 Voltmeter (Vsense1 and Vsense2)
6.4 Measurement Non-Linearity
6.5 Shutter/Trigger
The Ossila Source Measure Unit has two additional voltage measurement channels marked as Vsense1 and
Vsense2. They are designed to accurately detect small voltages while simultaneously having a wide dynamic
range of ±10 V. Table 6.5 lists the specications of these additional channels.
The non-linearity in the measurement of the Ossila Source Measure Unit is kept well below the
measurement accuracy of every range. Such non-linearity is common due to dierent amplication stages
and analogue digital conversion processes.
The Shutter/Trigger can be used either as an input or an output. It can be used to send a trigger signal to
other instruments or congured to wait for a trigger from other instruments. The voltage level of the Shutter/
Trigger is 5 volts and can source and sink up to 30 mA of current; higher currents may result in damage to
the unit.
Warning: Do NOT apply currents to a SMU that are greater than the maximum current of the range
that is active, as this may result in damage to the unit.
Note: the Vsense module shares a ground plane with the SMU module of the same number (i.e.
Vsense 1 shares a ground plane with SMU 1) and hence is not isolated.

The Ossila Source Measure Unit is designed to work with any network that supports DHCP. When the
ethernet cable is plugged in, the unit will automatically detect and identify the network and register itself
within a few seconds.
For most networks, the unit will need no further work – simply plug in and wait for the DHCP to work, and it is
ready to go. However, there are two situations where more steps are required:
(I) Networks Requiring Registering Devices
Some large corporate networks (such as universities) have increased security levels and will only allow
“known/registered” devices onto the network. If this is the case for your network, you will need to register
the MAC address rst. After this, the unit should be allowed on the network and will work as normal via
DHCP (fully automatically from this point with no intervention). Many institutions have their own registration
systems for computers and printers, and usually have online instructions on how to register a device. If
needed, the MAC address of the unit can be obtained by connecting to it with the Front Panel software
over USB.
(II) Static IP Networks
For a network without DHCP support, a static IP address must be set manually. This can be done by following
these steps:
1. Connect the Source Measure Unit to a PC using a USB cable.
2. Disable the DHCP client of the device using the command “eth0 set dhcp false”.
3. Set the IP address and other network parameters using the command “eth0 set network ip-address
subnet-mask gateway-ip dns-ip”.
4. Save the changes to the board so that they are loaded when the device powers on using the
command “eth0 save network”.
5. Disconnect the USB cable, then connect the Ethernet cable and the device should connect after
a few seconds.
Alternatively, an external network router that supports DHCP can be used to connect to a static IP network.
1. Run the le ‘Ossila-Front-Panel-Installer-vX-X-X-X.exe’ on the USB memory stick provided.
2. Follow the on-screen instructions to install the software.
