This model has been replaced by the MDO-2102A!
The GW Instek GDS-2102E is a 2-channel oscilloscope and the 100MHz version in the GDS-2000E series from GW Instek. The unique part for the GDS-2000E scopes is that they feature an AD converter for each channel. This means the sampling speed doesn't have to be divided between the channels and the scopes offer a sampling frequency of 1 MS/s per channel. This means that when using the scope on two channels it'll offer the same performance as 2 GS/s scope would normally.
With the 4 channel scopes the AD converters are split between channel 1 and 2, and 3 and 4 separately. So when channels 1, 2 and 3 are in use, the first two will operate in 500 MS/s mode, and channel 3 will continue to function as a 1 GS/s channel.
Scopes in the GDS-2000E series feature a large 8" colour display. With a 10 Mpts/channel memory depth there is plenty of space to store signals with high precision. With the 120.000 wfs/s capture rate signals can be analyzed quickly with these scopes. Compared to the SDS2000 scopes these scopes offer some better features.
The scopes can be connected to a computer using USB or LAN for data storage or analysis. Apart from that a usb stick can be connected with which data can be logged up to 100 hours straight. This data is stored in a csv file, which can be used by for example matlab or excel. Data can be printed directly on printers that support PictBridge.
Using the built in voltage meter RMS values up to 3 digits precise can be displayed. Apart from that the scopes feature a 5 digit frequency counter to clearly measure the frequencies that make up the signal.
The GDS scopes offer very low background noise of only 400 µVpp in the signal processing. Backgound noise strongly influences the accuracy when measuring small signals.
The scopes offer Dual-display functionality, making it possible for viewing both the entire signal and a small part of it at the same time. Using this feature the properties of the signal can be easily analysed since it gives more detailed overview.
Models ending in 2 feature 2 channels, the ones ending in 4 offer 4 channels. Apart from the amount of channels the models within one series have similar features.
