Comb Generator PG10

Short pulses with a pulse width ≤30ps
Repetition rates from below 1MHz up to 2.56GHz
PRBS sequences of length 2ⁿ-1 with n= 4, 5, 6, 7, 8, 9, 10 or 11.
Minimal phase variation

The comb generator PG10 generates pulse trains with a maximum repetition rate of 2.56GHz. An external clock signal between 480MHz and 2.56GHz is needed to provide the time base for operation. Two different operation modes are available, that can be selected via the instruments USB-interface:
In frequency divider mode the instrument generates output pulses according to the input clock frequency divided by one of the dividers /1, /2, /4, /8, /16, /32, /64 , /128, /256 or /512.
In PRBS mode pulses are generated according to the pseudo random binary sequence of length 2ⁿ-1 with n= 4, 5, 6, 7, 8, 9, 10 or 11.
The comb generator provides short negative output pulses with a fixed pulse width ≤30ps and minimal phase variation.

Broadband 100 GBit/s 4:1 Multiplexer MUX 100G

Broadband 4:1 Multiplexer for Serial Data Rates between 4 GBit/s and 100 GBit/s
Single-ended Data and Clock Inputs
Internal Delay for Timing Control
400mV Output Amplitude (single-ended)

The Sympuls multiplexer MUX 100G operates gap-free at data rates between 4 GBit/s and 100 GBit/s. A clock signal of half the output data rate is used to multiplex the four parallel data input signals into a serial output data stream of up to 100 GBit/s. All data and clock inputs are single-ended and DC-coupled allowing the generation of arbitrary data patterns even with long sequences of consecutive zeros or ones. The divided clock signal is generated internally and available at the clock outputs for driving the input pattern generator or as trigger signal. The adjustable delay allows to control the timing of the input data, if the clock output signal is used for driving the input pattern generator.

Differential Line Impedance Analyzer D-TDR 3000

Differential Line Impedance Measurement (D-TDR)
3 GHz System Bandwith
Temperature-stable Time Base with 1 ps Resolution
Analysis of Transmission Lines up to 1000m Length
Localization of Cable Faults and Mismatches
Propagation Time and Cable Length Measurements
Powered by USB

The handy sized line impedance analyzer D-TDR 3000 is used for the analysis of various lines and allows the precise localization of cable faults, shorts and termination mismatches. The impedance variation as a function of transmission line length is shown in graphical form on the screen of the connected computer. The combination of a fast push-pull pulse generator with a rise time of less than 100 ps and a sampling scope of 5 GHz bandwidth leads to a system-bandwidth of more than 3 GHz.
