The Tektronix 7A24 is a 400 MHz dual-channel vertical plug-in for 7000-series scopes with (fused) 50 Ω BNC inputs.
The 7A24 would typically have been used in 7834, 7844 or 7854 mainframes. The recommended probes were the P6056 and P6057.
The 75 MHz 7A18 and 200 MHz 7A26 share the same front panel layout and operation (but have 1 MΩ inputs).
Key Specifications
| Bandwidth | 400 MHz (71xx) / 350 MHz (79xx) / 300 MHz (78xx) |
|---|---|
| Deflection | 5 mV/Div to 1 V/Div (1–2–5) |
| Input impedance | 50 Ω |
| Maximum input | 5 V (0.5 W) - no damage below 10 V (2 W) |
| Timing | Delay difference between channels < 200 ps |
Internals
The 7A24 uses the Tek-made differential amplifier 155-0078-10.
The 7A24 does not use the ±50 V supplies provided by the mainframe.
