Price on request
Request a quoteThe 87237 series uses thermocouple detection to measure average power of CW and modulated signals. Models D, L and P cover DC–18 GHz, DC–67 GHz and DC–110 GHz, respectively; accuracy varies by model and band.
Series appearance reference showing multiple models. It does not imply that a set of sensors is included. The supplied model and connector are defined in the quotation.
Models and measurement ranges
| Manufacturer model | Frequency range | Power measurement range |
|---|---|---|
| 87237D | DC–18 GHz | −35…+20 dBm |
| 87237L | DC–67 GHz | −35…+20 dBm |
| 87237P | DC–110 GHz | −30…+20 dBm |
Accuracy and conditions
Accuracy conditions: −15…+20 dBm, DUT SWR<1.20 and averaging count 128. Zero-setting and measurement noise have increasing effects below −15 dBm.

- ±0.16 dB applies only to the 87237D DC–8 GHz band under the stated conditions, not to every model and frequency.
- Stored calibration data and parameters do not remove periodic calibration requirements under a customer quality system.
- L/P VSWR specifications start at 100 kHz and are not extrapolated to DC–100 kHz. A DC measurement range does not imply the same VSWR specification at DC.
- Test/calibration services are model-specific options. For 87237P, a calibration report is offered below 67 GHz and a test report for 67–110 GHz; these are different documents.
Options and quotation
English labels, manuals and software are model-specific -H12 options. Calibration reports and extended-warranty services are quoted separately, not assumed included. Specify model, signal type, power range, connector needs, accessories and quantity. Scope of supply and delivery schedule are defined in the quotation.
