The MS710C/D/E/F is a family of high-performance microwave spectrum analyzers spanning 10 kHz to 23 GHz, with an optional measurement range up to 140 GHz when external mixers are used. The design pairs a simplified PLL synthesizer local oscillator with a two-channel digital memory and supports both easy manual operation and fully automatic operation over GPIB. Operator-focused design choices include a grouped key layout with key sizes scaled to functional importance, an operation guide display for complex SHIFT and MARKER sequences, and a preset memory that holds up to 10 sets of measurement conditions.
The series is applied to spectrum analysis of microwave devices and components; spurious emission and spectral distribution measurements of analog and digital communications transmitters; interference measurements for radio stations, satellite earth stations, and similar installations; spectrum analysis in basic research such as nuclear physics and radio-astronomy; and spurious measurements for home-use satellite broadcast receivers and related equipment.
ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we have specialized in new and used test and measurement equipment since 1992. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding our own stock lets us match the right instrument and condition to each application and ship promptly from our own shelves.
The MS710C/D/E/F is a four-model microwave spectrum analyzer series that shares a common architecture — the same resolution bandwidth range, marker and memory functions, display, and GPIB automation — while differing in frequency coverage and frequency accuracy. All four models cover the 100 kHz to 2 GHz and 1.7 to 23 GHz bands; the variations between models concern the low-frequency band, the external-mixer extension to 140 GHz, and whether the model includes high frequency accuracy.
Because the core measurement functions are common across the family, the choice between models comes down to the required frequency span and accuracy class rather than a difference in operating workflow. The comparison table below summarizes how each model is configured.
Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the specific model that matches your required frequency coverage and accuracy, then choose the pre-owned listing that fits your budget and lead-time needs.
The MS710C covers the widest frequency range in the series: it is the only model that adds the 10 kHz to 30 MHz band, and it combines high frequency accuracy with external-mixer support that extends measurement coverage up to 140 GHz.
The four models differ along three axes. The MS710C provides the 10 kHz to 30 MHz band, high frequency accuracy, and external-mixer extension to 140 GHz. The MS710D covers 100 kHz to 23 GHz with external-mixer extension to 140 GHz. The MS710E covers 100 kHz to 23 GHz with high frequency accuracy.
High frequency accuracy is provided on the MS710C and MS710E, while external-mixer operation up to 140 GHz is supported on the MS710C and MS710D. Refer to the comparison table for the per-model frequency coverage and accuracy details.

| MS710C | 10 kHz to 23 GHz | 18 to 140 GHz | Yes |
| MS710D | 100 kHz to 23 GHz | 18 to 140 GHz | No |
| MS710E | 100 kHz to 23 GHz | — | Yes |

Important: Maximum input level: +30 dBm, ±0 Vdc.
Important: 18 to 140 GHz measurements on the MS710C and MS710D require an external waveguide mixer, which is not supplied with the instrument and must be ordered separately. When using a 3-port external mixer, an additional amplifier (such as the MP11975A) is required for local signal amplification.
Important: Local output for external mixer: 3 to 6 GHz, ≥+7 dBm; IF input for external mixer: 521.4 MHz.
Important: Power cord plug type must be specified at time of order.
Recommended pairing: the MH680A1 Tracking Generator and MH648A Pre-amplifier are offered as application equipment for the MS710 series.
