Use the 525 for accurately monitoring and measuring AM broadcasts signals with Hybrid Digital transmission, whilst off air providing even better measurement results

• Frequency-agile design gives accurate off-air measurements.
• Maintains AM accuracy with IBOC digital transmissions.
• Remote alarms for overmodulation, carrier loss and audio loss.

The Model 525 is our second-generation AM Mod-Monitor. It was specifically developed to give accurate AM readings with Hybrid Digital (IBOC) transmissions.

The 525 is menu-driven with a peak-hold LCD display showing simultaneous positive and negative modulation, incoming RF level and asynchronous noise. Measurement bandwidth extends to more than 10kHz, but a programmable low-pass audio filter can simulate the response of consumer radios or the effects of transmission bandwidth constraints.

The 525 is supplied with an outdoor large aperture loop antenna.
