ISC-2425-25+

ISM Signal Generator & Controller

USB & I2C

50Ω -30 dBm to +25 dBm

2400 to 2500 MHz

Feature

Advantages

Dynamic range > 50 dB, the output power can

vary from -30 dBm to +25 dBm in 0.01 dB steps

Enables very precise power control into any applicator Course control: 0.5 dB and Fine control: 0.01 dB

Frequency selection: with 1kHz steps in the

2.4 – 2.5 GHz ISM band

This allows the optimum frequency for the application to be set

Phase setting with 1˚ resolution

When multiple signal sources are used in coherent mode power can be delivered very accurately

USB-based, serial communication interface

Enables easy connection and interaction with other system controller hardware or external computers

DC supply through a dedicated two-pin connector

or via a USB connector

An external DC supply enables higher power output (25 dBm) Versus 20 dBm when the supply voltage is

directly from the USB port

Internal low frequency (LF) 10 MHz clock can

be shared via an LVDS signal through the AUX

connectors

Enables coherent operation with other external hardware and other signal generator boards

Pulse modulation and CW operation.

PWM duty cycles in 1% steps, ranging from

1 – 99 %. The default PWM frequency is 1 kHz

These different power output modes of the ISC-2425-25+ allow the user to fine-tune the power to their

application

Fast minimum reflected power lock and tracker

Supports optimized and efficient power delivery into any application or load by monitoring the reflected

power in real-time

Closed loop mode (DLL)

The Digital Locked Loop (DLL) is an algorithm on the ISC board’s microcontroller. It tunes the RF signal

towards the best-matched frequency within a user-defined frequency range. The DLL is suitable for driving

applications with changing impedance conditions

Feed forward (open loop) mode

In this mode, the autogain feature of the controller is switched off, and the user must determine the output

power manually

Chain/coherent mode

Allows an ISC board to be configured as stand-alone or master or slave in a chain of ISC controllers. This is

useful for specific use cases such as phase-coherent heating

Integrated powerful microcontroller

Capable of accommodating the board control firmware and user-defined application-level SW

Application programmer’s interface

The user can create their control program to control the RF generator

Power amplifier status inputs

The user can read the calibrated RF power, current and temperature measurements from Mini-Circuits

connectorized amplifiers such as the ZHL-2425-250X+

Embedded memory

The user can store calibration data, use-case profiles, modulation patterns etc.

Dedicated I2C functions

Enables easy communication with connected power amplifier modules such as the ZHL-2425-250X+

Fast reflected power sweep across the frequency

band (2.4 to 2.5 GHz)

Allows the user to adapt the system in real time to dynamic load conditions

Safe operating area (SOA), (configurable, fast

protection algorithms)

Allows the user to set limits to ensure the power amplifier is protected against thermal and RF overstress
