1009 Fixture enables 50 A to be applied to an SMD inductor
Stable component fixturing ensures high accuracy and
repeatable measurements. Enclosed fixtures, with safety
interlocks, minimises risk to operators.
Technical specifications
The 3265B series of DC bias units must be used in conjunction
with either a 3260B, 3255BL, 3255B or 3255BQ.
Compliance voltages
Maximum compliance voltage (<12 kHz) 11 V DC at 0.25 V AC
drive level.
10 V compliance at 1 V AC drive level. For f>12 kHz deduct 0.5 V.
Applications
Permits measurement analysis of wound components with levels of
DC bias current higher than the standard 1A
Variable measured
In impedance mode: L, Z, R, Q, D.
Not applicable to Rdc, or transformer measurements
Measured frequency range
3255BL 20 Hz to 200 kHz (3265B/5A or 3265B10A only)
3255B: 20 Hz to 500 kHz
3255BQ: 20 Hz to 1 MHz
3260B: 20 Hz to 3 MHz (with 3265BQ/25A)
Basic accuracy
± 1%, Varies with measurement speed, frequency and options
chosen.
Measurement terminals
2-terminals measurement via M8 studs.
4-terminal measurement via Kelvin leads and M8 studs.
Measurement terminals internally protected by 1.6A fuses against
normal inductor back-EMF or accidental disconnection of inductor.
Front panel fuses easily replaced.
Control connections
I
2
C bus link controls application of DC current and monitors
status of analyzer. Status data includes excessive voltage drop
and over temperature
Optional facilities
3265B bias units may be connected in parallel to give five
times the rated current.
Interlock
Bias safety interlock socket on rear panel of analyzer provides
door lock and closed control lines
Temperature range
Storage: -40°C to 70°C.
Operating: 0°C to 40°C 20 A (3265BQ/25A and 3265B/25A )
Full accuracy: 15°C to 30°C (at maximum rated current)
Power supply
