Which PhonoVibe do you need?
The range is one instrument in four sizes. What separates them is channel count, sample rate and bandwidth — and the measurement you have to make usually decides it for you.
Start from the measurement
Route measurement, bump testing, single-point survey
One sensor plus a tachometer reference is all a walk-around route or a bump test needs.
Two-plane balancing, FRF, driveline and NVH work
Two-plane balancing needs two response channels plus a reference; FRF needs force and response together.
Multi-point survey, small modal tests, end-of-line rigs
Enough simultaneous channels to capture a small structure in one shot instead of roving and re-referencing.
Modal analysis, structural dynamics, large arrays
The flagship — a full array captured simultaneously, which is what a clean mode shape depends on.

Identical across the range
These do not vary by model, so they are not reasons to choose one over another.

Questions about choosing a model
- What is the real difference between PhonoVibe D and the rest?
- D samples at 48 kHz over 2 Hz – 20 kHz with a ±10 V input; Q, O and HD sample at 128 kHz over 0.5 Hz – 60 kHz with a ±5 V input. So D is not simply "fewer channels" — the wider bandwidth on the larger units matters for bearing and gear work at the top end, and their lower corner matters for slow-speed machines.
- Can I start with 2 channels and add more later?
- The channel count is fixed per unit, so a second unit is the way to add channels rather than an upgrade. If there is any prospect of two-plane balancing or FRF work, the 4-channel Q is usually the cheaper decision over the life of the instrument.
- Do all four use the same sensors and software?
- Yes. Every model is 24-bit, supplies 24 V, 4 mA constant current (IEPE/ICP/CCLD), reads TEDS, and ships with the TVIB TSAP201 base module. A sensor bought for one works on any of them.
- What is PhonoVibe Eco X?
- A 4-channel unit bundled with a 20 N shaker as one bench — built for teaching labs, where the exciter and the DAQ are bought together and used in the same experiment.
- What do they cost?
- PhonoVibe D ₹1,36,080, PhonoVibe Q ₹2,88,000, PhonoVibe O ₹4,60,800, PhonoVibe HD ₹7,20,000. Indicative and ex-works, excluding GST — the binding figure is the quotation.
