Description
The PCIe-7841 data acquisition board by National Instruments features 8 analog input channels with a resolution of 16 bits and a sampling speed of 200 kS/s. It also offers 8 analog output channels with a resolution of 16 bits and an output rate of 1 MS/s, making it ideal for precise and fast signal acquisition and generation in various applications.
The PCIe-7841 is a model of data acquisition board manufactured by National Instruments. It is equipped with an onboard FPGA (Field-Programmable Gate Array) known as Virtex-5 LX30. One of the important specifications of this device is its part number, which is 781100-01. This unique identifier helps in identifying and distinguishing this particular model among others in the product line. In terms of analog input capability, the PCIe-7841 offers 8 channels. These channels can be configured as differential, referred single-ended (RSE), or non-referred single-ended (NRSE). The board supports a resolution of 16 bits and can sample signals at speeds of up to 200 kS/s. Additionally, it has a voltage range of +10 V, allowing for a wide variety of analog input applications. Similarly, the analog output feature of the PCIe-7841 consists of 8 single-ended channels. It supports a resolution of 16 bits and can produce output signals at rates of up to 1 MS/s. The voltage range for analog output is 0.5 V. This data acquisition board from National Instruments combines high-performance analog input and output capabilities with the flexibility of onboard FPGA technology. It is suitable for applications that require precise and fast signal acquisition and generation, such as industrial automation, scientific research, and test and measurement applications.

Distribution Cache Shipping Info and Options
Shipping Carriers: Here at Distribution Cache we ship using UPS, FedEx, DHL, or TNT. In most cases we get very competitive rates based on our volume and will be happy quote shipping cost to your location upon request. We also know that many customers would prefer to ship collect on their own account numbers and welcome this option.
Shipping Blind: We recognize that many of our customers intend to re-sell the product to their end user. We respect our customer’s relationships with their clients and offer blind shipping as an option to ensure that the package arrives in the most clandestine way possible.
Shipping Process: We take pride in the way we package your order and spare no cost in making sure that it arrives safely at your facility. In the case of new parts, we are always sure to package the factory box inside another larger box for safe transit. For reconditioned parts we often use Distribution Cache customized packaging that is specially made to protect the products from the bumps and falls present during shipment.
Shipping Options:
Next Day Air Early AM - This service is the fastest overnight delivery option available. For most locations the package will be guaranteed by 8:30AM.
Next Day Air – This service guarantees delivery by 10:30AM and is the most frequently used option for overnight shipments.
Next Day Air Saver – This cost saving overnight alternative guarantees delivery by 3PM the next day.
2nd Day Air – For domestic shipments that would take 3-5 days if shipped via Ground, sometimes having the order in 2 days is a great way to go
Ground – Ground is the most inexpensive shipping option provided. Please ask if we are doing a “free domestic ground” shipping promotion on your order. We often provide free ground shipping on larger orders.
Emergency Courier – At times we can help work with a courier service to get the part to your facility during downtimes scenarios. We prefer that the customer sets up the courier but we can be there to make sure the product is handed off to the driver. Please give us a call to see if this is an option on your order.
Please Note: Products listed as “ships today” can ship same-day if an order is placed before 4PM. For larger drives and motors we ask that notification for same-day shipments be provided by 2PM at the latest. For any products listed as “ships in 3-5 days”, please give us a call to see if this can be expedited.
