• Fast, easy, and accurate full two-port calibration
• Supports 1.85 mm connectors

The Keysight N4694D microwave electronic calibration (ECal) module makes calibration of Keysight vector network analyzers fast, easy and accurate. The N4694D is a precision 2-port ECal module that supports 1.85 mm connectors up to 67 GHz. Select either female-female, male-male, or female-male connectors. The plastic storage case for the N4694D is included for securing your ECal module and accessories.

The N4694D Option 0DC extends the calibration frequency range down to DC, which is beneficial for broadband device modeling or time domain and signal integrity analysis using enhanced time domain-analysis on the Keysight network analyzers.

This ECal module is an ideal solution for calibrating vector network analyzers. Performing a full two-port calibration takes less than half the time and number of connections versus traditional mechanical cal kits. The operator simply connects the ECal module to the vector network analyzer via USB and the firmware controls the rest, thus reducing the chance for operator error. Wear and tear on connectors is reduced as well, lowering repair costs on both the test port connectors and calibration standards.

• Até 30 GHz

O adaptador de osciloscópio de amostragem N5477A faz com que o sistema de sondagem InfiniiMax III fique completamente compatível com a família de osciloscópio de amostragem Infiniium DCA 86100. Com o N5477A, os módulos DCA possuem 30 GHz de sondagem, aumentando seu desempenho e flexibilidade.

Anteriormente, o osciloscópio de amostragem de banda larga DCA-j era limitado em 13 GHz de sondagem, porém com o adaptador N5477A e a ponta de prova InfiniiMax III, o DCA-j pode operar até 30 GHz.

O N5477A também pode ser utilizado para conectar a ponta de prova InfiniiMax III a um equipamento de teste genérico de 50 Ω, tal como um analisador de espectro, desde que sejam utilizados a fonte de alimentação 1143A e o adaptador NMD macho-3,5mm fêmea 5062-1247.

• Impedância nominal: 50 Ohms
• Faixa de frequência: CC a ≥ 26,5 GHz
• Queda de tensão ± 0,6 a 0,7 V (±10 mACC)
• Nível de dano ESD (apenas limitador: 2400 V usando o modelo de corpo humano)
• Nível máximo de dano de potência de RF (+ 17 dBm)
• Voltagem máxima de entrada/saída CC = ± 5V
• Corrente máxima de entrada/saída = ± 80 mA

As especificações acima são valores típicos e não garantidos

O N9355CK01 é um limitador de diodo que protege os canais sensíveis de osciloscópio dos danos causados por estresse de sobrecarga elétrica (EOS) e descarga eletroestática (ESD). Por exemplo, tensões em excesso de ±2V podem destruir os amostradores de alto desempenho utilizados em osciloscópios. O limitador reduz drasticamente a probabilidade de tais tensões alcançarem a parte sensível do instrumento, garantindo que o osciloscópio funcione de forma confiável por mais tempo.

Os instrumentos com dois canais elétricos, como o 54754A, precisam de dois N9355CK01s. Os geradores de passo dos módulos de TDR utilizam ≤ 0,2 V, o que é bem menor do que o limiar de diodo do limitador N9355CK01. O N9355CK01 também pode ser utilizado para proteger o canal elétrico do 86105X e módulos similares, desde que o sinal não exceda a faixa de -0,5V a +0,5V.

N1021B Differential Time-Domain Reflectometry and Time-Domain Transmission

• Bandwidth 18 GHz
• 100 Ohm nominal differential impedance
• Variable tip spacing: 0.0-2.54mm
• Spring-loaded probe tips with independent Z-axis movement

N1021B Differential Time-Domain Reflectometry and Time-Domain Transmission Probe Kit Details

The N1021B is an ergonomically designed handheld probe to interface TDR/TDT modules to printed circuit boards (PCBs) and components that lack common coaxial high-frequency connectors. The built-in wheel adjusts the pitch between the differential tips to make good contact with pads or access points spaced from closed to typical IC pins (2.54 mm).

Engineers working on high-speed differential electrical channels can analyze where the device under test (DUT) causes reflections that unfavorably affect the signal integrity (SI) of their designs. Manufacturers of printed circuit boards (PCB) can control process consistency from batch to batch, and/or locate the position of shorts, opens, or other flaws.

The N1021B probe is used in conjunction with the DCA-X Wideband Oscilloscope Mainframe, the 54754A Differential and Single-ended TDR-TDT Module, and the N1055A35/50 GHz 2/4 Port TDR/TDT Remote Sampling Head. The N1021B probe launches small electrical steps in the DUT (device under test) and/or receives the response, which is processed and displayed in the time domain or as S-parameters (SDD11, SDD22, SDD21, or SDD22). Time-domain measurements can display the reflected voltages or observed impedances versus time or distance. S-parameter measurements include magnitude, phase, and group delay.

N1027A is a collection of accessories for DCA-X mainframes, modules and stand-alone DCA-Ms in Keysight's Digital Communication Analyzer (DCA) family. The accessories can be grouped into:

• Kits including multiple parts for specific applications (e.g., N1027A-46A for the N1046A 100+ GHz Electrical Remote Sampling Heads)
• Individual components needed for measurements (e.g., N1027A-PT2/PT3 phase trimmers to adjust skew between electrical channels)
• Items for protection and storage (e.g., N1027A-1MC storage case for mini-modules with remote heads)
