SIGELNT 二、 Upgrade Via Guide Procedure Upgrade via guide procedure also can be used if the method above does not work. Specific steps are as follows: 1. Press the knob and simultaneously turn on the instrument. It will now enter the guide procedure mode. 2. After entering the guide procedure mode, the upgrade method is the same as in the previous procedure.
SIGELNT Chapter 3 Remote control 3.1 Control method Based on NI-VISA Users can remotely control the instrument by using NI-VISA from NI (National Instruments Corporation). In regards to NI-VISA, there is a full version and a live version (Run-Time Engine version). The full version includes NI device drivers and a tool called NI MAX. NI MAX is a user interface that controls the device. The real-time version is much smaller than the full version and includes only NI device drivers.
SIGELNT basic communication technology in computer networks. It allows applications to communicate through network hardware and the standard network protocol built into the operating system. This method requires two-way communication between the instrument and the computer network through an IP address and a fixed port number. SPD1000X Socket communication port is 5025.
SIGELNT Brackets ({}) contain parameter choices. Brackets are not sent with the command string. Vertical line (|) separates parameter selections. Angle brackets (<>) indicates that you must specify a value for the parameter inside the brackets. For example, for the parameter in angle brackets for the above command, you must specify a value for this parameter (for example, "CH1: VOLT 10"). Angle brackets do not send angle brackets along with the command string.

SIGELNT Chapter 4 Common troubleshooting The most commonly encountered failures and their solutions are listed below. Please use these steps listed if an error occurs. If the problem persists, please contact SIGLENT . 1. The instrument will not power on. (1) Check whether the power is correctly connected. (2) Check whether the power switch at the front panel is on.
SIGELNT 3. The constant current output is abnormal. (1) Check whether the maximum output power of the scale currently selected fulfills the load requirement. If yes, go to the next step. (2) Check whether the cable connecting the load and power supply is short-circuited and is making good contact. (3) Check whether the load is normal. (4) Check whether the voltage setting value of this scale is proper; if it is too low, increase it properly. (5) If the problem persists, please contact SIGLENT.
