Key Features
Overview
The OMICRON‑Lab B‑AMP 12 is a broadband source power amplifier designed for the Bode 100. It provides 12 dB (×4) gain from DC to 50 MHz, raising the source up to 25 dBm for demanding transmission and impedance measurements. Dedicated impedance measurement ports (CH1/CH2) support direct pickup for impedance and monitoring without external splitters.
Why Consider It
When characterising very low impedances, voltage‑dependent components, or systems operating in noisy environments (e.g., power converters), a higher stimulus level improves measurement signal‑to‑noise ratio. B‑AMP 12 enables these higher levels while maintaining 50 Ω interfacing and flat response. It is optimised for the Bode 100 ecosystem and measurement methods used in loop gain, input and output impedance, and S‑parameter work.
Key Details
Frequency range DC–50 MHz; gain 12 dB; max output 25 dBm; 50 Ω I/O; high return loss; 10–36 VDC supply. The amplifier’s CH1/CH2 ports provide defined attenuation for safe pickup. For impedance workflows, refer to the Bode 100’s supported methods. If using other accessories (e.g., injection transformers or PDN probes), ensure voltage limits and calibration best practices are observed.

Frequently Asked Questions
Have a Question?
-
What are the mechanical and power specs?
138×75×32 mm, ~0.21 kg, 10–36 VDC supply; BNC connectors; 50 Ω I/O.
-
Can it aid loop gain measurements?
Yes, more injection power improves loop gain analysis in power converters and op‑amp systems with proper injection points.
-
Which impedance methods benefit most?
Low‑Z methods like 2‑port shunt‑thru benefit from higher drive to overcome noise and cabling losses.
-
Does software auto‑detect B‑AMP 12?
No, the amplifier is passive to the instrument; levels follow Bode 100’s source settings (13 dBm in equals ~25 dBm out).
-
What protections or limits apply?
Input ≤1 VRMS; output up to 25 dBm; reverse power damage 1 W; observe DUT and instrument voltage limits.
-
How does it compare to a high‑end RF power amplifier?
Generic RF amps often lack DC coupling and dedicated pickup ports; B‑AMP 12 is DC–50 MHz with CH1/CH2 tailored for measurements.
-
Does B-AMP 12 improve measurement accuracy?
It improves SNR; accuracy still depends on calibration, fixtures, and method (e.g., shunt‑thru for low‑Z).
-
Do the CH1/CH2 ports simplify impedance measurement?
Yes, they provide defined attenuations and return loss for direct pickup and impedance workflows without external splitters.
-
When should B-AMP 12 be used?
Use when measuring very low impedances, voltage‑dependent components, or in noisy environments where higher SNR is needed.
-
What does B-AMP 12 do with Bode 100?
It provides 12 dB gain from DC–50 MHz so the Bode 100 can drive up to 25 dBm for S21 and impedance tasks.
