Despite our hopes and effort to create an innovative and low-cost T&M solution, we’ve received consistent negative feedback on the OpenScope MZ and OpenLogger regarding overall reliability that has led us to determine that it is not up to our high standards for our test and measurement products.
Unfortunately, we are unable to fix many of the issues, so we have made the difficult decision to pull both products, and related accessories from our shelves. This will allow us to ensure we can continue to deliver on the Digilent brand promise and focus our efforts on expanding our popular and core line of Test and Measurement Products.
The materials on this page will remain here as legacy sources. Any Digilent provided support for this material will be extremely limited at best. Thank you for understanding.
OpenLogger参考手册
OpenLoggeris a wireless data logging and data acquisition device that can be controlled via USB or WiFi. Using a computer or mobile device, signals from circuits and sensors can be acquired, stored, analyzed, visualized, and generated. OpenLogger makes it easy to monitor multiple analog inputs and simultaneously log the data to an SD card, and/or stream over USB or WiFi, all throughWaveForms Live。

Walk Around the Board
软件Support
TheDigilent Agent和WaveForms Live用于与OpenLogger以及查看捕获的数据进行配置和通信。可以在上面链接的各自的资源中心上找到更多信息,以及OpenLogger资源中心。
重要的!
The OpenLogger can only be used with Windows operating systems.
Analog Inputs
模拟输入提供了从外部系统中测量真实模拟数据的方法。OpenLogger拥有8个单端模拟输入,并具有自己的建议地面销。每个输入旨在接受-10 V至+10 V的电压范围(保护高达±30 V),并具有12位分辨率和50的带宽kHz。openlog可以记录所有数据到本地SD card at 500KS/s, stream and/or log data over USB at 500KS/s, or stream and/or log data over WiFi at 10 kS/S.
模拟输入具有以下功能:
-
8 Channels
-
12 bits of resolution per channel
-
500KS/s聚合输入
-
50kHzbandwidth at -3 dB
有关如何使用OpenLogger的模拟输入的信息,请参见OpenLogger的Data Logger教程。
Function Generator
OpenLogger有一个单个通道2MS/s, 10-bit function generator. An R2R resistor ladder with 1% resistors is used in place of aDAC。
功能生成器支持:
-
Sine, triangle, sawtooth, square and DC outputs
-
10-bit resolution
-
1Hzto 200kHzfrequency
-
3 V pk2pk output with ±1.5 V offset
-
20 mA output current
Information on how to use the OpenLogger's Function Generator can be found in the OpenLogger'sFunction Generator教程。
Digital I/O
数字I/O提供通用输入和输出,以检测并提供检测和提供高逻辑状态的方法。OpenLogger有8个用户IO引脚,可用于一般使用。
Information on how to use the OpenLogger's Digital I/O can be found in the OpenLogger'sDigital I/O教程。

Troubleshooting
LED指标
The LEDs on the OpenLogger are used to indicate the current status of the OpenLogger hardware as follows:
-
橙色 - 设备正在引导,尚未准备好使用。
-
Green Flashing - Device is booted and ready to use, but not logging.
-
Green Solid - Device is logging to the内存buffer and streaming is currently available.
-
Green and Orange Solid - Device is both logging and streaming.
-
绿色固体和橙色闪烁 - 设备正在流到内存缓冲区,但登录到SD卡或通过WiFi停止
-
For the SD card, this usually indicates there is no more space on the SD card
-
-
Red Solid - One of the internal buffers was overrun
-
Filling the SD card does not cause an overrun condition
-
-
Red Flashing - Warning that the device is falling behind with keeping the buffers cleared
-
蓝色固体 - 保留用于wifi(尚未实施)
-
Red blinking and Orange Solid - Device firmware updating
-
