    Using Model DMM7510 TSP-Link commands with other TSP-Link products If you are connecting the Model DMM7510 in a system with other TSP-Link products, be aware that some of the TSP-Link commands may be different. You can use the earlier versions of the commands, but be aware that they may not be supported in future versions of the product.

  • Page 299: Tsp-Net

    Using TSP-Net commands with TSP-enabled instruments, a Model DMM7510 can download a script to another TSP-enabled instrument and have both instruments run scripts independently. The Model DMM7510 can read the data from the remote instrument and either manipulate the data or send the data to a different remote instrument on the LAN.

    To communicate to a remote ethernet device from the Model DMM7510: 1. Connect to the remote device using one of the above procedures. If the Model DMM7510 cannot make a connection to the remote device, it generates a timeout event. Use tspnet.timeout to set the timeout value.

    If the Model DMM7510 is connected to a TSP-enabled instrument through TSP-Net, all events that occur on the remote instrument are transferred to the event log of the Model DMM7510. The Model DMM7510 indicates events from the remote instrument by prefacing these events with “Remote Error.”...

At these rates (lowest noise region in graph), the Model DMM7510 will make corrections for its own internal drift and will still be fast enough to settle a step response of less than 100 ms.

  • Page 306: Dmm Resistance Measurement Methods

    The method that the Model DMM7510 uses to measure resistance depends on the resistance range. For resistance ranges from 1 Ω to 1 MΩ , the Model DMM7510 uses the constant-current method to measure resistance. For resistance ranges from 10 MΩ to 100 GΩ, a ratiometric method is used.

  • Page 312: Magnetic Fields

    Some systems may still have residual thermoelectric offsets after following the guidelines in Minimizing thermoelectric EMFs (on page 4-8). If the offsets are relatively constant, you can use the relative offset feature in the Model DMM7510 to cancel them. Refer to Relative offset (on page 3-4) for information.

  • Page 313: Radio Frequency Interference

    In extreme cases, a specially-constructed screen room may be required to sufficiently attenuate the RFI signal. In some situations, the Model DMM7510 digital filter may help to reduce RFI effects. In some cases, additional external filtering may also be required. However, filtering may have detrimental effects, such as increased settling time on the signal.

  • Page 991: How Do I Save The Present State Of The Instrument

    Why did my settings change? Many of the commands in the Model DMM7510 are saved with the measure function that was active when you set them. For example, assume you have the measure function set to current and you set a value for display digits.

  • Page 992: What Is A Configuration List

    If you are using TSP, configuration lists run faster than a script that is set up to configure the same settings. The Model DMM7510 supports measure configuration lists, making it possible to sequence through defined measure settings. Each configuration list consists of a list of configuration indexes. A configuration index contains all instrument measure settings that were active at a specific point.

  • Page 1004: Common Commands

    This section describes the general remote interface commands and common commands. Note that although these commands are essentially the same as those defined by the IEEE Std 488.2 standard, the Model DMM7510 does not strictly conform to that standard. The general remote interface commands are commands that have the same general meaning, regardless of the instrument you use them with (for example, DCL always clears the GPIB interface and returns it to a known state).
